I think the changes will be substantial, both for Python code and for
C extensions.

A biggie is going to be the replacement of immutable str for binary
data; that gets replaced with a mutable bytes object.  It'll be good
to have, but the loss of an immutable sequence-of-bytes type seems
like a problem to me.

On the other hand, we gain ordinary string literals being Unicode.

I'm not sure what will happen with the standard library; it's just too
early to say.  I don't actually expect huge changes there, aside from
changes required by the str->bytes replacement.
