%s, because it is the most general, has the most convoluted resolution:

      pass it straight through

It should try to get a Py_buffer instead.

Meaning any bytes or bytes-subtype will support the Py_buffer protocol, and 
this should be the first thing we try?

Sounds good.

For that matter, should the first test be "does this object support Py_buffer" and not worry about it being isinstance(obj, bytes)?


    - input type is numeric?
      use its __xxx__ [1] [2] method and ascii-encode it (strictly)

What is the definition of "numeric"?

That is a key question.

Obviously we have int, float, and complex.  We also have Decimal.

But what about Fraction? Or some users numeric class that doesn't inherit from a core numeric type? Wherever we draw the line, we need to make it's well-documented.
