Summary Sloppy mode function declaration in block unable to access lexical variable

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).

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.
