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).
x**= (n, 10) # exponentiation to a tuple isn't currently defined, and it
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.
