This may seem like a minor nit -- and it is, in some ways -- but I think reminding people of the pedagogical issues involved in the transition is important. Granted, this is python-dev, so we should be using 2.x syntax, but we're currently talking about 3.0 and that requires clarifying what is meant/intended. -- Aahz (aahz at pythoncraft.com) <*> http://www.pythoncraft.com/ "It is easier to optimize correct code than to correct optimized code." --Bill Harlan
