Re^2: How can I see a CPAN module's print message

But why? As I can do it like this: MyPackage.pm

 use strict;
use warnings;

{
    package MyPackage;
    use Carp;
    carp "print message";

}
1;

main.pl

use MyPackage;

Also consider that Perl will load the first file `TieRegistry.pm` it finds in `@INC`. Inspect the values of `%INC` to find out which file Perl loaded, and which one you edited. See perlvar and Data::Dumper. `use TieRegistry; print Dumper \%INC;` [download]	[reply] [d/l] [select]

That line will print because it's not in a sub. A line inside a sub can only print when that sub is actually executed. (The exception to this rule being a line that is evaluated at compile time. But it would be unusual to do this.) `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply]

Yes, so my print or carp in file scope(I mean not in any sub) should print the message if I "use" it I think.	[reply]

well, filehandles can be redirected, die/warn can be trapped, see %SIG, Carp::Always, Devel::Trace ...	[reply]


Do you know where your variables are?
