Re^3: How do I curtail the noise

Perl uses %INC to keep track of require'd files. On case-insensitive file systems, you can load the same file under more than one name. For example:

use Strict;
[download]

loads strict.pm but never calls its import method.

And is it useful to be able to have a `strict.pm`? I note that putting `use Carp; use carp;` [download] in a module isn't flagged by perlcritic. Should this be an error, either of style or of syntax?

There is no use to having Perl load "both" `Strict.pm` and `strict.pm`, especially if they both end up being the same file on some filesystems. But that that's possible is a side effect of hash keys (like in %INC) being case-sensitive and file systems sometimes being case-insensitive. I can't come up with a useful use for that. Having two modules whose names only differ in case is non-portable at least, and in my opinion could always be flagged as a potential error. But then, I avoid Perl::Critic, so I wouldn't know how to implement it.	[reply] [d/l] [select]
