Re: [Python-ideas] Proposal to add new built-in struct (was: Add kwargs to built-in function object)

The implementation:

class struct (object):

I think it makes the most sense, if this construct is adopted, to use __slots__ to control mutability. Someone more well-versed in the python object model should determine if this is actually a good idea. -- Cheers, Leif
