Bug 15216 – Produce clearer error messages w.r.t. ref

ref int foo(ref int x) { return x ; } void main () {     foo(3) ; // Error: function rvalue_argument.foo (ref int x) is not callable using  argument types (int) // Comment: "argument ref int x of function rvalue_argument.foo cannot bind  to an rvalue" would be clearer IMO     int i ;     ref ir = i ; // Error: variable ref_type.main.ir only parameters or foreach declarations  can be ref // Comment: after the variable name add a colon, and add ", return values"  after "parameters" }
