=head2 Pragmatic Modules They work somewhat like compiler directives (pragmata) in that they tend to affect the compilation of your program, and thus will usually work well only when used within a C, or C. Most of these are lexically scoped, so an inner BLOCK may countermand them by saying: no integer; no strict 'refs'; no warnings; which lasts until the end of that BLOCK. Some pragmas are lexically scoped--typically those that affect the C<$^H> hints variable. Others affect the current package instead, like C and C, which allow you to predeclare a variables or subroutines within a particular I rather than just a block. Such declarations are effective for the entire file for which they were declared. You cannot rescind them with C or C. The following pragmas are defined (and have their own documentation). =over 12 =item * B<<< L<< attributes >> >>> - Get/set subroutine or variable attributes =item * B<<< L<< autodie >> >>> - Replace functions with ones that succeed or die with lexical scope =item * B<<< L<< autodie::exception >> >>> - Exceptions from autodying functions. =item * B<<< L<< autodie::exception::system >> >>> - Exceptions from autodying system(). =item * B<<< L<< autodie::hints >> >>> - Provide hints about user subroutines to autodie =item * B<<< L<< autouse >> >>> - Postpone load of modules until a function is used =item * B<<< L<< base >> >>> - Establish an ISA relationship with base classes at compile time =item * B<<< L<< bigint >> >>> - Transparent BigInteger support for Perl =item * B<<< L<< bignum >> >>> - Transparent BigNumber support for Perl =item * B<<< L<< bigrat >> >>> - Transparent BigNumber/BigRational support for Perl =item * B<<< L<< blib >> >>> - Use MakeMaker's uninstalled version of a package =item * B<<< L<< bytes >> >>> - Force byte semantics rather than character semantics =item * B<<< L<< charnames >> >>> - Define character names for C<\N{named}> string literal escapes =item * B<<< L<< constant >> >>> - Declare constants =item * B<<< L<< deprecate >> >>> - Perl pragma for deprecating the core version of a module =item * B<<< L<< diagnostics >> >>> - Produce verbose warning diagnostics =item * B<<< L<< encoding >> >>> - Allows you to write your script in non-ascii or non-utf8 =item * B<<< L<< encoding::warnings >> >>> - Warn on implicit encoding conversions =item * B<<< L<< feature >> >>> - Enable new features =item * B<<< L<< fields >> >>> - Compile-time class fields =item * B<<< L<< filetest >> >>> - Control the filetest permission operators =item * B<<< L<< if >> >>> - C a Perl module if a condition holds =item * B<<< L<< inc::latest >> >>> - Use modules bundled in inc/ if they are newer than installed ones =item * B<<< L<< integer >> >>> - Use integer arithmetic instead of floating point =item * B<<< L<< less >> >>> - Request less of something =item * B<<< L<< lib >> >>> - Manipulate @INC at compile time =item * B<<< L<< locale >> >>> - Use and avoid POSIX locales for built-in operations =item * B<<< L<< mro >> >>> - Method Resolution Order =item * B<<< L<< open >> >>> - Set default PerlIO layers for input and output =item * B<<< L<< ops >> >>> - Restrict unsafe operations when compiling =item * B<<< L<< overload >> >>> - Package for overloading Perl operations =item * B<<< L<< overloading >> >>> - Lexically control overloading =item * B<<< L<< parent >> >>> - Establish an ISA relationship with base classes at compile time =item * B<<< L<< re >> >>> - Alter regular expression behaviour =item * B<<< L<< sigtrap >> >>> - Enable simple signal handling =item * B<<< L<< sort >> >>> - Control sort() behaviour =item * B<<< L<< strict >> >>> - Restrict unsafe constructs =item * B<<< L<< subs >> >>> - Predeclare sub names =item * B<<< L<< threads >> >>> - Perl interpreter-based threads =item * B<<< L<< threads::shared >> >>> - Perl extension for sharing data structures between threads =item * B<<< L<< utf8 >> >>> - Enable/disable UTF-8 (or UTF-EBCDIC) in source code =item * B<<< L<< vars >> >>> - Predeclare global variable names (obsolete) =item * B<<< L<< version >> >>> - Perl extension for Version Objects =item * B<<< L<< vmsish >> >>> - Control VMS-specific language features =item * B<<< L<< warnings >> >>> - Control optional warnings =item * B<<< L<< warnings::register >> >>> - Warnings import function =back =head2 Standard Modules Standard, bundled modules are all expected to behave in a well-defined manner with respect to namespace pollution because they use the Exporter module.
