Thanks. Speaking of Cows, the first time playing after tracking down some real skunk dice, I was playing with my little nephew and my dad. When he had to leave for a moment, I switched one of the skunk dice for a cow die. Daniel could barely conceal his excitement at the joke, and sure enough, dad rolled a Cow on his next turn, and played it up nicely.

Seriously, I'm glad you like the extension mechanism. I'm not convinced that it's "elegant" in a large software engineering sence -- it should use normal Perl objects. But I think this is handy in reducing the amount of work that needs to be done, and avoiding the need to put more than one package in a file. So it's "elegant" in some other sence of the word, like a perl -e line that lets you replace a whole program with a one-liner.
