I'm guessing Collin Winter designed it when he implemented the first
half of PEP 3134. (There is no mention of these APIs in the PEP.)
Looking at the source code it looks like all the cases so far where
these are actually used, this API is actually fortunate -- in all
cases I've found the ownership for the argument needs to be passed
into the exception object anyway.
There are some precedents, e.g. PyList_SetItem().
