(for Simo)
If namespace pollution extends to single characters why not just use _ as
the function name. Even looks like a "null" name.
def _(arg): print arg
If they're intended as throwaways for sending to another function or
putting in a dict:
def _(arg): print arg
def __(arg): print arg
def ___(arg): print arg
def ____(arg): print arg
someMap = { "a": _, "a": __,"a": ___,"a": ____ }
(Though personally I can't see the harm in giving a temporary function a
name, much like you often give intermediary values in a function names)
