What about type (really type) inference? :-) There have been some interesting projects looking at the matter of checking types in Ruby (not based on class/module membership), including one by Eivind and I think one by Florian Gross. It's not easy... but anything less is, I think inevitably and almost by definition, going to reduce what one can do in Ruby. David -- David A. Black dblack / wobblini.net
