As others have said, to import a selected set of functions or to import
functions not in the default import.
Also:
use Carp qw( :all );
Will import everything. Most modules (standard modules and CPAN ones)
will have the tag `:all` to import everything.
If you don't want to import any:
use Carp ();
To use a function in Carp, you would use the fully-qualified name:
Carp::croak "ribbit";
