If only one trailing "given" clause can be given per `if` test

I was actually thinking that if we did want to allow multiple assignments,
and we limited targets to single names, we could just use a comma as a
separator:
if diff and g > 1 given diff = x - x_base, g = gcd(diff, n):
return g
Similar to import statements, optional parentheses could be included in the
grammar, allowing the name bindings to be split across multiple lines:
if diff and g > 1 given (
diff = x - x_base,
g = gcd(diff, n),
):
return g
I'm well behind, but... this! This turns "given" into a +0.8 for me.
That's really nice. It reads clearly too.
I was hitherto in the "expression as name" camp, which I gather is already
rejected.
