Need Help??

in reply to Using a module more than once

Is this bad practice? Will it hurt anything? (I assume "no" to both questions, but I could be wrong.)

I don't think so, unless these modules do something really strange. In which case you would probably already know from their documentation. See e.g.:

#! /usr/bin/perl -l

use strict;
use warnings;
use lib sub { print pop; undef };

use File::Find;
use File::Basename;
use File::Find;

__END__

which gives me

File/Find.pm
warnings/register.pm
Cwd.pm
vars.pm
XSLoader.pm
File/Basename.pm
re.pm
File/Spec.pm
File/Spec/Unix.pm
Scalar/Util.pm
List/Util.pm
DynaLoader.pm
AutoLoader.pm

I've never seen a sub ref being passed to `use lib` before. How does that work? I also don't see anything in the docs about it. Is it an unintended consequence (accidental feature? :-) or am I just out of date? Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.

perldoc -f require will explain it better than I ever could. It was a big discovery for me too. Of course you can exploit this feature to do more {bizarre,uselful} things.	[reply]

Thanks! That's the kind of factual confirmation I was hoping to get.	[reply]
