Dear Brethren and Sisters,

with the following code

#!/usr/bin/perl

use strict;
use warnings;

my $val = $Some::Nonexistent::Pkg::variable;
[download]

Perl tells me (exactly as expected):

$ ./warnme.pl
Name "Some::Nonexistent::Pkg::variable" used only once: possible typo 
+at ./warnme.pl line 6.
$ _
[download]

When putting this same code in a module I would have expected to be warned similarly. However, no messages, nothing. Even quieter than Perlmonks on weekends.

___ ./WarnMe.pm ___

package WarnMe;

use strict;
use warnings;

my $val = $Some::Nonexistent::Pkg::variable;

1;
[download]

___ ./warnme.pl ___

#!/usr/bin/perl

use strict;
use warnings;

use WarnMe;

# ...
[download]

___

$ ./warnme.pl
$ _
[download]

Is this the way it's supposed to work? Can't I take advantage of this used only once: possible typo warn facility within modules? I couldn't find anything related in the docs...

( I've been playing with this for a while now, and although, for the life of me, I can't tell what I'm doing wrong, I have that sneaking feeling this is going to be something embarrassing for me in one way or another... But what the heck? Your chance to tell a little chick how Perl really works ;)
