Off topic: why can't we simply allow something like this:
(the_bob) = (name for name in ('bob','fred') if name=='bob')
Why does Python treat the parenthesis at the LHS as grouping parens?
operators are not allowed anyway; (a + (b + c)) = [1] is syntax error.
Currently
(x) = 1
works, but I can't see why should it.
