Without the use statement I get:

No such class wolf at demo.pl line 22, near "my wolf"
syntax error at demo.pl line 22, near "my wolf="

You're missing some $'s ...

my $wolf=new sheep;
print $wolf->bleet()."\n";

    --k.

This, and you need ref($proto) not ref{$proto} (parentheses not braces).

The reason for this error message is a bit more obscure. (It has to do with something called "indirect object syntax".) However, the error goes away if turn the bareword wolf into the scalar $wolf.

  my $wolf=new sheep;
     ^

I suspect this is what you had in mind.

Obviously my brain is feeling unpunctuated today. Thank you all for the $help. Sorry to be a pain but any ideas on why I get a

Can't locate object method "bleet" via package "HASH" at demo.pl line

See Kanji's earlier response.

Perl requires a certain eye to punctuation. For a free language, it is surprisingly insistent on seeing dollar signs in the right places.
