in thread normal objects?

tadman, the part you describe is easier than I thought it would be. But (pardon me for thinking out loud - I promise to read the docs) what if $bessie has the $bessie->eat method, prior to re-blessing and a new $bessie->eat method after the conversion by grind()? Am I confusing myself, or, won't there be a conflict?

Yes there will be a conflict. You will need this as well: `package Beef; use vars qw(@ISA); #if you use strict @ISA = qw(Cow);` [download] Which is why it's wise to plan out your inheritance tree before you start coding. OOP is only as good as its design. To be technical, Beef IS NOT a Cow - a Cow HAS Beef. Take a look into aggregation for alternatives to inheritance.

package Beef;

use vars qw(@ISA);    #if you use strict
@ISA  = qw(Cow);
