The special syntactic form doesn't bother me that much. '**dict' is
already a syntax error in many places, but allowed in a few other places.
I also do not think the purpose served is important enough to warrant a new
special form. The actual same conciseness can be achieved with a function
that does just a little bit of magic, e.g.:
func(**Q(u, v))
Someone linked to a library that apparently does the magic a bit better
than my 5-minute version (which required quoting the variable names). I
think it was you who complained that sys._getframe() might be CPython
specific, which is true. But probably other implementations could do
different magic to make their own Q(), so that seems of little importance.
I really doubt I'll ever use a magic function like Q()... but the fact that
I could have done so for the entire 20+ years that I've used Python tends
to emphasize that the need isn't REALLY that huge. And if the need isn't
large, reserving new syntax for it isn't compelling.
