Unfortunately (AFAIK) the symbol mangler doesn't take const into account 
yet, so it's impossible to overload like that until mangling is changed. 
:( I suspect Walter is hesitant to completely break library 
compatibility from D 1.0 to D 2.0! That's the problem with const 
correctness... gotta do it all the way or not at all... ;)
