in reply to Alternative ways to fully qualify subroutine names

the more subs I import the harder it becomes to keep track of where they are all from

You could import the sub to a different name:

*vlp_func = \&Very::Long::Package::func;

Update: The following is a means of doing the above with a large number of functions:

use warnings; use strict; sub import_func { my ($src_name, $dst_name) = @_; if (not defined $dst_name) { $dst_name = (split(/::/, $src_name))[-1]; } if (index($dst_name, '::') < 0) { $dst_name = caller() . '::' . $dst_name; } my $src_func_ref = do { no strict 'refs'; \&$src_name }; my $dst_glob_ref = do { no strict 'refs'; \*$dst_name }; *$dst_glob_ref = $src_func_ref; } sub Foo::Bar::func { print("Hello World!\n"); } import_func('Foo::Bar::func', 'fb_func'); fb_func(); # Calls Foo::Bar::func

To import multiple functions at once, you can use

import_func("Foo::Bar::$_", "fb_$_") foreach qw( func moo bla );
