lambda: x := (lambda y: (z := (a := 0)))
As I say, it's the only *possible* parsing. It's ugly, and it
absolutely should be parenthesised, but there's no need to make the
parentheses mandatory. (And actually, it didn't take me long to add
those parentheses, it's not *hard* to parse correctly - for a human).
