The use statement is roughly[1] equivalent to saying
BEGIN {
require "modulename";
modulename->import(@_);
}
The part that is tripping you up is the require. Require
searches the paths in @INC for a file named modulename.pm.
Failing to find that file it exits with an error. The
require functions job is to load the file, since the code
you want is already part of the file the require is not
necessary. This means you can replace your normal use
statement with
BEGIN {
modulename->import(any args you would have passed to use);
}
1. if you say
use packagename ();
it is equivalent to
BEGIN {
require 'packagename';
}
