Making TypeInfo.next() return a const(TypeInfo) was a bad idea

[Benjamin Thaut]

Because you are now no longer able to do stuff like this:

void log(...)
{
   auto t = _arguments[0];
   while(some condition)
   {
     t = t.next();
   }
}

To be actually able to use TypeInfo.next you will now need the ConstRef 
(hack) from phobos. Afaik there is no such thing in druntime which makes 
working with TypeInfo.next within druntime a real pita.

Any suggestions?

Kind Regards
