Hi,

I have a OO framework of several modules, and dozens of programs that make use of these modules. In each module I always start with the same lines.

use strict;
use Data::Dumper;
use Carp;
[download]

My question is, is it really needed to import Data::Dumper and Carp in every package file?
Does it have a noticable performance impact?

If it is use'd once (f.e. in my constructor class, which is called by every program in its ISA structure), I should be able to call Dumper by referring to Data::Dumper::Dumper,isn't it.

What is the best practice for this?

I have (not yet) any long running daemon.

I hope this question is clear enough.
