However there's quite a bit of Python 2.x code around that manipulates bytes in the guise of 8-bit strings, and it uses tests like "if s[0] == 'x': ..." frequently. This can of course be rewritten using a slice, but not so easily when you're looping over bytes:

for b in bb: if b == b'x': ...

Would it make anything easier if there were a character literal?

for b in bb: if b == c'x': ...

where c'x' is another way of writing ord(b'x').

An advantage of this is that it would make Py3k compatible with Pyrex, which already has c'x' literals. :-)
