Which make me wonder what plans there are for providing a better
mechanism than default arguments as a way of initializing local function
variables. Nested def's to create a closure with initialized values is
pretty crufty for that, IMO. Maybe extending the default argument space
with whatever comes after e.g. a triple star delimiter in the argument list,
but which wouldn't be counted as part of the normal arguments? E.g.,
def foo(x, y=123, *args, **kw, *** i=1, deftime=time.ctime()):
return x*y, kw.get('which_time')=='now' and time.ctime() or deftime
Seem like a minor extension of the default-arg hack.
