in thread How can I get Perl via Carp, to SCREAM -- more informative output via cluck(),confess(),longmess()?

Undefined subroutine &main::confess

This is because you forgot to import the confess function. You're importing cluck, longmess and shortmess but nothing else from Carp:

use Carp qw(cluck longmess shortmess);

Really, longmess and shortmess are unlikely to be much use in end-user code. They might be helpful if you were writing an extension to Carp.

The four functions that are actually useful are croak, confess, carp, and cluck, and the least useful of these is cluck (which happens to be the only one of them that you're importing).

use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name

    Good points, tobyink.

    I should have caught the omission of confess, myself. Thanks for pointing it out. <blush>

    Thanks again.

    Hey. I'm not completely useless. I can be used as a bad example.
