But you already know that it is called 'foo'! :)
Anyway I don't think it has anything to do with lambda:
>>> def x(): pass
>>> y = x
IIRC, in 2.4 you can set the func_name attribute so you could set up a
decorator to set the name for you. Or if you want to be fancy you could
even set up a metaclass that automatically renames all the lambda
functions it finds in a class.
