My apologies; I didn' have the source, so I was going by memory. :)

This one uses instance_eval:

  http://saxa.georgetown.edu/~jack/ruby/rosa/meth.php?c=1

and was also posted on Rubygarden at:

Yours uses send(), which can be almost as bad if not used carefully.
It's also a lot simpler and easier to understand than a solution that
doesn't allow calls to private methods.

BTW, I think there's a typo in the online source.  Line 18 should be
changed from:
  @curObj[-1].send(methname, args)
.to:
  @curObj[-1].send(methname, *args)
