Yes - this is my definition of parallelism as well:
true concurrency, not perceived (as in preemption,
context switching, and so on).

The question is: does any Lisp do this with `let'?

If yes, that Lisp could do it partly with let* as well
only that would imply an overhead to sort out where
there are precedence constraints.

The appeal of doing it for let is that it wouldn't be
any fuss - just distribute, compute, and execute the
body all set. But if no one did it, some practical
obstacle must still have gotten into the way...
