By default, LET creates lexical bindings, which means they're only
visible to code lexically within its body. Since the body of that
closure is outside the LET, it cannot access the local binding. You'd
need to declare X special in the LET and the closure for them to find
each other (most implementations will do this automatically for the
closure, because they can see that there's no surrounding binding of the
free variable, but you still have to make it explicit for the LET).
