Usually the lack of distinction between function and method is a problem in Perl, but here it means that you can use can() on a package name even if it's not a class and get back a subroutine reference even if it's not a method.

package My::Awesome::Package;

use 5.010;

sub foo { ... }
sub bar { ... }
sub baz { ... }

package main;

for my $func (qw( foo bar baz quux ))
{
    next unless my $func_ref = My::Awesome::Package->can( $func );
    say "Found code for '$func': ", $func->();
}
