Sloppy mode function declaration in block unable to access lexical variable

[Adam Klein]

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.
