It *does* implement that! So there's the solution: these APIs should
not insist on bytes but use the buffer API. It's quite a bit of work I
suspect (especially since you can't use PyArg_ParseTuple with y# any
more) but worth it.
BTW PyUnicode should *not* support the buffer API.
I'll add both of these to the task spreadsheet.
