Python to Drop filter() and map()?

Guido van Rossum is thinking out loud about saying bye bye to lambda, reduce(), filter(), and map(). No comment on the first two -- but filter and map are pretty much obsolete thanks to generator expressions and conflict with the most natural names for two objects of the GIS problem domain. This proposed change won't guarantee that we never again see myMap in Python mapscript code, but it would be a start.
