[issue32012] Disallow ambiguous syntax f(x for x in [1],)

[Stefan Krah]

Stefan Krah <stefan at bytereef.org> added the comment:

I think "ambiguous" is not the right word. If a single argument
can be a non-parenthesized generator and all arguments can be
followed by a trailing comma, it's clear.

The language spec is often behind in my experience.
