Currently, most mutating bytearray methods only accept integers as items (in 3k, in 2.6 they also accept single-char strings, for a reason I can't remember).

Single-index assignment accepts anything compatible with operator.index(). This should be made consistent, but in which direction? I think they should all made to go through operator.index(). BTW, looking at the 3.0 code, I was initially a little confused. While the term 'item' generally refers to the value of a list or sequence, several functions in bytearrayobject.c seem to be using it for an argument that can be either an index or a slice. Notably bytessubscript() and bytesass-subscript() have this confusing terminology. This is unrelated but you might want to fix this too.

OK, fixed in trunk and 3k. One consequence is that bytearray("xyz") is no error in 2.6 -- I hope this is what was intended in the first place.
