It sounds like you're talking about some language other than Io, or didn't delve deeply enough into it, since Io makes no such requirements. The attribute and method (not made distinct in Io; they're called "slots") is much the same as with Python; the current instance is checked for the object, then its parents, then _its_ parents, and so on. -- Erik Max Francis && [EMAIL PROTECTED] && http://www.alcyone.com/max/ San Jose, CA, USA && 37 20 N 121 53 W && AIM, Y!M erikmaxfrancis No man quite believes in any other man. -- H.L.
