[issue23201] Decimal(0)**0 is an error, 0**0 is 1, but Decimal(0) == 0

[Stefan Krah]

Stefan Krah added the comment:

The behavior is already documented (power function):

  "at least one of x or y must be nonzero"


The decimal docs are already so large that it is probably a bad
idea to add a warning.
