As explicitly defined in the language reference, the "negative"
operator has lower binding precedence than the "power" operator
<URL:http://www.python.org/doc/ref/summary.html>.

It does, if you actually have a negative number that you're raising to
power 0.

    >>> (-123)**0
    1

The parser is operating according to the documented language
specification. It can't account for the user being fooled by external
sources.
