+1.  This is what Python 3.x does to help manage the same transition: the
only string APIs that don't have bytevector counterparts are formatting,
string-to-bytevector conversion, and a few others.  This API is also
useful for dealing with binary protocols that have ASCII parts.

If I understand the docs correctly, the Python regular expression module
handles both strings and bytevectors, but a match target and the pattern
being matched must have the same type.
