Yes.  Can an expression statement *start* with a labeled expression?

  label : { ... }
  (expression) . f ();

Is the parenthesized expression an argument to the labeled block expression
(which must be of function type), or the start of a new statement?

We can go on and on here, but the fundamental point is: it is a bad idea to
have a single syntax be ambiguous between a statement form and an expression
form.
