    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;
     ^

      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 
+23.

        See Kanji's earlier response.

        ? (Is this my cargo finally coming home?)

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