You can hop through the symbol table at runtime. The following code is a bit ugly, but it works with my testing: 
#!/usr/bin/perl -w

use strict;

my $name = "chromatic";
my $quest = "nefarious symbol wrangling";

sub findme {
    # just has to be defined
    return 0;
}

foreach (keys %main::) {    # use whichever package you prefer
    no strict 'refs';        # else the next line fails
    if (defined *{$_}{CODE}) {
        print "$_\n";        # could be pushed onto an array, into a h
+ash
    }
}

The trick is knowing that you can access a symbol table with %main:: or %packagename:: or %:: for the current package.

The typeglob trickery in the defined line just looks to see if there's a CODE bit in the current package.

Personally, I'd just keep a hash of subroutine names and references around: 

my %subs = (
    mod_disk => \&mod_disk,
    mod_ram => \&mod_ram,
    mod_sticky_note => \&mod_sticky_note,
    mod_gum_wrapper => \&mod_gum_wrapper
);
