Description:
Perl pragma for subroutine signatures
signatures is a Perl pragma that provides a simple and robust way to declare named parameters for your subroutines. It provides a syntax similar to Perl function prototypes (see perlsub) and is robust since it does this without using source filters. It also provides a way to combine these signatures with normal Perl prototypes.
