Can pragma(mangle, ...) be used on types? Then we can define a 
C/C++ compatible `HeadConst` template that simulates C/C++ const 
semantics, while still being mangled correctly:

template HeadConst(T) {
     pragma(mangle, const(T).mangleof)
     struct HeadConst {
         // @disable opAssign();
         // and whatever else is necessary for head-const
     }
}

The constructor would of course need to make sure that it accepts 
only types with non-const indirection.
