Bug 13944 – Built-in stringof and mangleof properties are unnecessarily fixed to the type 'string'

Example code: struct S {} string cs = S.stringof; // OK wstring ws = S.stringof; // NG dstring ds = S.stringof; // NG The reason is that 'stringof' property makes a suffixed string literal "S"c rather than "S". The literal type is enforced to 'string' by the suffix, so it cannot be converted to '[wd]string'. The same issue exists on mangleof property. string cm = S.mangleof; // OK wstring wm = S.mangleof; // NG dstring dm = S.mangleof; // NG I think the restriction should be lifted.
