[Python-3000] pre-PEP: Default Argument Expressions

[Guido van Rossum]

Nobody has asked me yet, but I'm not going to support this PEP. it's
too big a departure from existing semantics. Next are we going to turn
class variables initialized with expressions into automatic instance
variable initializers implicitly executed in the __init__ code?
Newbies are just as likely to run into the aliasing problem there as
in the argument default case.
