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... -- underground experts united
