Logged In: YES user_id=80475 Other than consistency is there a reason for the patch? I understand that str.count and list.index both have optional start/stop arguments, but those both have use cases. AFAICT, no real-world use cases have been presented for list.count with start/stop arguments. A quick grep of the standard library does not reveal ANY code that would be improved as a result of this patch. The proposal does have some minor disadvantages: 1) complicating the signature and docs, 2) introducing a inter-version incompatability, 3) slowing the method call (changing from METH_O to METH_ARGS). Unless some offsetting benefits are shown, this patch should probably not be accepted.
