The first version of PEP 293 changed the errors argument to be a string
or callable. This would have simplified handler stacking somewhat
(because you don't have to register or lookup handlers) but it had the
disadvantage that many "char *" arguments in the C API would have had to
changed to "PyObject *". Changing the errors argument to a list of
strings would have the same problem.
