Jean,

Hmm. This looks close, but the :test in your example can only be a
variable that has been defined within the instance_eval...and I need to
pass one from outside. 

The others run, but add the method to the class, rather than the
instance of that class.

I'm sure there's a simple way. I just can't see it.
