If I have a .pm file, is there a way I can use it, without placing it on my @INC path? I think that would be clearer in my particular use case - clearer than using relative paths or adding this directory to @INC.

Edit: Clarification:

I was hoping to avoid the necessity to iterate through every item in @INC, and instead specify directly which file I am interested in. For example, in Node.JS, require('something') will search the list of paths, but require('/specific/something') will go directly where I tell it to.

In Perl, I am not certain that this is the same functionality found in require, but it seems to work.

However, use statements require barewords. That has left me a little stumped on how to enter an absolute path.

You can use this :

use lib '/path/to/Perl_module_dir'; # can be both relative or absolute
use my_own_lib;

You can modify @INC by yourself (temporarily, no fear, that's what use lib does too) :

BEGIN{ @INC = ( '/path/to/Perl_module_dir', @INC ); } # relative or absolute too
use my_own_lib;
