A sigil, followed solely by digits matching \p{POSIX_Digit}, like $0, $1, or $10000, A sigil, followed by either a caret and a single POSIX uppercase letter, like $^V or $^W, or a sigil followed by a literal control character matching the \p{POSIX_Cntrl} property. Due to a historical oddity, if not running under use utf8, the 128 extra controls in the [0x80-0xff] range may also be used in length one variables, Similar to the above, a sigil, followed by bareword text in brackets, where the first character is either a caret followed by an uppercase letter, or a literal control, like ${^GLOBAL_PHASE} or ${\7LOBAL_PHASE}, A sigil followed by a single character matching the \p{POSIX_Punct} property, like $! or %+

DECOMPRESS the file, UNPACK the file into a directory, BUILD the module (sometimes unnecessary), INSTALL the module
Look around, Check it's new, Discuss the need, Choose a name, Check again
Start with module-starter or h2xs, Use strict and warnings, Use Carp, Use Exporter - wisely!, Use plain old documentation, Write tests, Write the README
Get a CPAN user ID, perl Makefile.PL; make test; make dist, Upload the tarball, Announce to the modules list, Announce to clpa, Fix bugs!
