Those two are independent of each other. Carp provides ways for you, the
programmer, do emit warnings and error messages. They'll show up no
matter whether warnings are in effect. Warnings on the other hand will
make the Perl interpreter emit messages when it has encountered
something warnings-worthy. It's the same as with warn(): You use that
indepently from warnings, too.

Yes, this is correct.

That's up to you. Carp exports carp() and croak(). I usually end up
needing both after a while.
