NAME Sub::Prototype::Util - Prototype-related utility routines. VERSION Version 0.03 SYNOPSIS use Sub::Prototype::Util qw/flatten recall/; my @a = qw/a b c/; my @args = ( \@a, 1, { d => 2 }, undef, 3 ); my @flat = flatten '\@$;$', @args; # ('a', 'b', 'c', 1, { d => 2 }) recall 'CORE::push', @args; # @a contains 'a', 'b', 'c', 1, { d => 2 }, undef, 3 DESCRIPTION Prototypes are evil, but sometimes you just have to bear with them, especially when messing with core functions. This module provides several utilities aimed at facilitating "overloading" of prototyped functions. They all handle 5.10's "_" prototype. FUNCTIONS "flatten $proto, @args" Flattens the array @args according to the prototype $proto. When @args is what @_ is after calling a subroutine with prototype $proto, "flatten" returns the list of what @_ would have been if there were no prototype. "recall $name, @args" Calls the function $name with the prototyped argument list @args. That is, @args should be what @_ is when you define a subroutine with the same prototype as $name. For example, my $a = [ ]; recall 'CORE::push', $a, 1, 2, 3; will call "push @$a, 1, 2, 3" and so fill the arrayref $a with "1, 2, 3". This is especially needed for core functions because you can't "goto" into them. EXPORT The functions "flatten" and "recall" are only exported on request, either by providing their name or by the ':funcs' and ':all' tags.
