Don't you mean clojure has a MORE robust indication of scope than other languages? In clojure you can nest lets, and it is very obvious when the binding is out of scope, but in c-style languages, once bound, they stay bound till the end of the function.

Nope, Nimrod (at least) has full lexical scopes if you want

    proc foo(x: int): int = 
      let z = x * 2
      #z visible
      block:
        let y = z * 4 #z & y visible
      let foo = 3 #z and foo visible, y out of scope

I said "c-style", not ML style.
