New submission from John O'Connor <tehj...@gmail.com>:
bytearray() is using a less efficient implementation of split() than its
similar friends bytes and unicode.
I added a couple extra checks to return early in {bytes,unicode} split().
- if length is 0
- if left strip removed all bytes
Looking at just how similar these 3 implementations are I feel that we could
also unify/generalize them into one generic helper implementation and leave the
object marshaling up to the type specific methods.
