Are you seriously proposing such a change? I was asking for
spellings that currently don't have a meaning (rather, I was
suggesting that no such spelling exists, and the entire idea
of supporting such notation in the language is ridiculous).

Likewise: it currenly is well-defined: it invoked nb_inplace_power
with the tuple (and __ipow__ if x's class is written in Python).
Whether this gives a TypeError or not depends on the class of x.
