This function expects constancy to be one of "const", "invariant" or "".

    string newType(string constancy, string oldType)
    {
        return constancy ~ "(" ~ oldType ~ ")";
    }

But I guess the real answer is aesthetics. We understand parentheses
to imply precedence, so naturally we expect the value expression (x)
to evaluate to x. It just seem intuitively write that the same should
be true of type expressions, that the type expression (T) should
evaluate to T.

This isn't a big deal. Say no if you like; I'm not going to argue
furiously for this one. It just seems aesthetically right.
