There's no syntactic ambiguity, so what guessing are you talking about?

What *really* requires guessing, is figuring out where in Python's
syntax parentheses are allowed vs not allowed ;). For example, "from
foo import (bar, baz)" is legal, but "import (bar, baz)" is not.
Sometimes it feels like Python is slowly and organically evolving into
a parenthesis-delimited language.
