Out of curiosity, what possible value can be derived from continuing to
enable implementations to ambiguously evaluate of code like:

 (let [(a (read in)) (b (read in))]
      (list a b))

or:

 (list (read in) (read in))

Personally I see none.

(If it's truly without virtue, the loophole should likely be closed).
