Test case:
{
let a = 42;
function f() { return a }
print(f())
}
This throws "ReferenceError: Can't find variable: a". If I run this in strict mode, it works as expected (printing 42).

We don't support this in global scope. We do support it inside functions and I believe eval. We still need to implement it for the global scope.
e.g, replace outer {} with function (and maybe eval) and it works.

Friendly ping. It's been a while, would be good to get this fixed.
