in reply to Accessing a scalar value in another subroutine?

Perhaps something like this, using Attribute-Handlers and putting the attribute in UNIVERSAL, which would, obviously, be optional:

package DocString; use Attribute::Handlers; use Data::Dumper; no warnings 'redefine'; our $docstrings; # sub Doc :ATTR(CODE) { sub UNIVERSAL::Doc :ATTR(CODE) { my ($package, $symbol, $referent, $attr, $data, $phase, $filename, + $linenum) = @_; $docstrings->{ $package }{ *{$symbol}{NAME} } = "@$data"; } # you could also have a docstring function exported from this module t +hat, given a package # and a sub returns # $DocString::docstrings->{$pkg}{$sub}); 1;

which could be used like this:

package Forble; use strict; use warnings; use DocString; sub veeblefaz :Doc("This method does the 2nd kind of veeblefaz operati +on!") { # this can be called from elsewhere, with the appropriate package +and sub names print Dumper($DocString::docstrings->{+__PACKAGE__}{veeblefaz}); + } 1;
