Such a weird spec, but your implementation makes sense. I can't think of a

Because the var scope is not in scope for parameters. Otherwise, e.g. this
function f() { return 1 }
function g(x = f()) {
// ...way down
var f = 2
}
would have a rather surprising result (g() === undefined). I'd actually be
fine
if this happened with var (just don't use it), but for legacy reasons, inner
functions are var bindings, too, unless inside a block.
