Pros for x.bits being a view:
- seems slightly cleaner (in my opinion)
- can potentially abstract slicing bits without copying the underlying int
(e.g. x.bits[2:][4:])
Pros for x.bits being a function:
- Victor's point
- no need to depreciate x.bit_length

Agreed.
Since type has __subclasscheck__ (why I don't know) this might result in a

Quick microbenchmark:

Since type has __subclasscheck__ (why I don't know)
Ouch, really? That means the PyType_IsSubtype path in PyObject_IsSubclass() is

I think we should add a tp_subclasscheck slot to minimize the general cost of
this. Also, try to see if there

Oh, sorry, I missed the workarounds when I read the issue. So your issue is
you want to use a lambda rather than a full function for the side effect and it

Yeah, and I'm not sure why they have their build pegged to bdb 4.6; they
