perltoc - perl documentation table of contents
This page provides a brief table of contents for the rest of the Perl documentation set. It is meant to be scanned quickly or grepped through to locate the proper section you're looking for.
Scalars, Arrays, Hashes
if, while, for, foreach
Arithmetic, Numeric comparison, String comparison, Boolean logic, Miscellaneous
Simple matching, Simple substitution, More complex regular expressions, Parentheses for capturing, Other regexp features
arrays of arrays, hashes of arrays, arrays of hashes, hashes of hashes, more elaborate constructs
use strictElapsed Real Time, User CPU Time, System CPU Time
Discontinuance, Deprecation, and BugFix traps, Parsing Traps, Numerical Traps, General data type traps, Context Traps - scalar, list contexts, Precedence Traps, General Regular Expression Traps using s///, etc, Subroutine, Signal, Sorting Traps, OS Traps, DBM Traps, Unclassified Traps
Symbols starting with "_" no longer forced into main, Double-colon valid package separator in variable name, 2nd and 3rd args to splice() are now in scalar context, Can't do goto into a block that is optimized away, Can't use whitespace as variable name or quote delimiter, while/if BLOCK BLOCK gone, ** binds tighter than unary minus, foreach changed when iterating over a list, split with no args behavior changed, -e behavior fixed, push returns number of elements in resulting list, Some error messages differ, split() honors subroutine args, Bugs removed
Space between . and = triggers syntax error, Better parsing in perl 5, Function parsing, String interpolation of $#array differs, Perl guesses on map, grep followed by { if it starts BLOCK or hash ref
Formatted output and significant digits, Auto-increment operator over signed int limit deleted, Assignment of return values from numeric equality tests doesn't work, Bitwise string ops
Negative array subscripts now count from the end of array, Setting $#array lower now discards array elements, Hashes get defined before use, Glob assignment from localized variable to variable, Assigning undef to glob, Changes in unary negation (of strings), Modifying of constants prohibited, defined $var behavior changed, Variable Suicide
Elements of argument lists for formats evaluated in list context, caller() returns false value in scalar context if no caller present, Comma operator in scalar context gives scalar context to args, sprintf() prototyped as ($;@)
LHS vs. RHS of any assignment operator, Semantic errors introduced due to precedence, Precedence of assignment operators same as the precedence of assignment, open requires parentheses around filehandle, $: precedence over $:: gone, Precedence of file test operators documented, keys, each, values are regular named unary operators
s'$lhs'$rhs' interpolates on either side, m//g attaches its state to the searched string, m//o used within an anonymous sub, $+ isn't set to whole match, Substitution now returns null string if it fails, s`lhs`rhs` is now a normal substitution, Stricter parsing of variables in regular expressions, m?x? matches only once, Failed matches don't reset the match variables
Barewords that used to look like strings look like subroutine calls, Reverse is no longer allowed as the name of a sort subroutine, warn() won't let you specify a filehandle
SysV resets signal handler correctly, SysV seek() appends correctly
@ always interpolates an array in double-quotish strings, Double-quoted strings may no longer end with an unescaped $, Arbitrary expressions are evaluated inside braces within double quotes, $$x now tries to dereference $x, Creation of hashes on the fly with eval "EXPR" requires protection, Bugs in earlier perl versions, Array and hash brackets during interpolation, Interpolation of \$$foo{bar}, qq() string passed to eval will not find string terminator
Perl5 must have been linked with same dbm/ndbm as the default for dbmopen(), DBM exceeding limit on the key/value size will cause perl5 to exit immediately
require/do trap using returned value, split on empty string with LIMIT specified

There must be no space after the << part, There (probably) should be a semicolon at the end of the opening token, You can't (easily) have any space in front of the tag, There needs to be at least a line separator after the end token
-i option from within a program? tail -f in perl? -i clobber protected files? Isn't this a bug in Perl?Comments Outside the Regex, Comments Inside the Regex, Different Delimiters
Solve the balanced text problem from another question in perlfaq6, Try the recursive regex features in Perl 5.10 and later. See perlre, Try defining a grammar using Perl 5.10's (?DEFINE) feature, Break the problem down into sub-problems instead of trying to use a single regex, Convince everyone not to use XML or HTML in the first place

release 1.94_57, bugfix: treat modules correctly that are deprecated in perl 5.12, bugfix: RT #57482 and #57788 revealed that configure_requires implicitly assumed build_requires instead of normal requires. (Reported by Andrew Whatson and Father Chrysostomos respectively), testfix: solaris should run the tests without expect because (some?) solaris have a broken expect, testfix: run tests with cache_metadata off to prevent spill over effects from previous test runs
Timely cleanup of SVs that are cloned into a new thread but then discovered to be orphaned (i.e. their owners are -not- cloned) (e42956), Don't accidentally clone lexicals in scope within active stack frames in the parent when creating a child thread (RT #73086) (05d04d), Avoid loading feature.pm when 'no 5.13.2;' or similar is encountered (faee19), Trap invalid use of SvIVX on SVt_REGEXP when assertions are on (e77da3), Don't stamp on $DB::single, $DB::trace and $DB::signal if they already have values when $^P is assigned to (RT #72422) (4c0f30), chop now correctly handles perl's extended UTF-8 (RT #73246) (65ab92), Defer signal handling when shared SV locks are held to avoid deadlocks (RT #74868) (65c742), glob() no longer crashes when %File::Glob:: is empty and CORE::GLOBAL::glob isn't present (4984aa), perlbug now always permits the sender address to be changed before sending - if you were having trouble sending bug reports before now, this should fix it, we hope (e6eb90), Overloading now works properly in conjunction with tied variables. What formerly happened was that most ops checked their arguments for overloading before checking for magic, so for example an overloaded object returned by a tied array access would usually be treated as not overloaded (RT #57012) (6f1401, ed3b9b, 6a5f8c .. 24328f), Independently, a bug was fixed that prevented $tied->() from always calling FETCH correctly (RT #8438) (7c7501)
