Do you think that the ‘int’ and ‘float’ types, which do produce a number
result for ‘0 ** 0’, are buggy and should be fixed?

I think the inconsistency is unnecessarily confusing. Perhaps the
consistency is in standards outside Python, but I think there is cause
here either for a change of behaviour or, if ther eis a good rationale
for the incompatible behaviours, to document the rationale. In either
case, a bug report is warranted IMO.
