[Python-Dev] bitwise operations for bytes and bytearray

Hi!
I'm interested in adding the functionality to do something like:
>>> b'a' ^ b'b'
b'\x03'
Instead of the good ol' TypeError.
I think both bytes and bytearray should support all the bitwise operations.
I've never hacked on cpython before. I'm starting by just trying to add xor
to bytearray. I have a ByteArray_Xor function that I think should do this
here
https://github.com/cowlicks/cpython/commit/d6dddb11cdb33032b39dcb9dfdaa7b10d4377b5f
But I'm not sure how to hook this in to the rest of cypython. I tried
adding it where bytearray_as_sequence is declared in this bytearrayobject.c
file. But that gave me compiler warnings and broke things.
So now that I have this ByteArray_Xor function, how do I make it be
bytearray.__xor___?
Thanks!
Blake
