Is it actually letrec, or is it letrec*? The example I referred to
(from the proposal page) would require letrec* semantics:
===
if (x > y)
{
let const k = 37;
let gamma : int = 12.7 + k;
let i = 10;
let function f(n) { return (n/3)+k; }
return f(gamma) + f(i);
}

It's not just the RI; the official proposal is very specific about let
semantics.
