Whitespace bugs? about wren HOT 4 OPEN

So the gotcha here is that "short hand return" is only valid if it's a single line.

x { _x } will return the contents of _x but the following will return null, which is the default in a method if nothing is returned by the end.

x {
  _x
  //implicit return null
}

what you're looking for is like this: because it's not a single line return shortcut, it must use the return keyword (otherwise it's just a "put the _x value on the stack and do nothing with it")

x {
  return _x
}

the inverse is also invalid, e.g x { return _x } is an error because the return isn't expected in a single line early return like that ✨

Thank you for clarification.

This 'shorthand return' behavior is actually documented for functions but not (AFAICS) for methods.

I'll do a PR to fix that.
