Transitive const sucks

I believe the intention was to keep it out of the language as it is an ambomination. That said, I'm not clear how you can get the proper semantics for e.g. overloads of [] in D without it.

I believe the issue of overloading opIndex and similiar is going to be 
taken care of using the 'return' storage-class (discussed in 
WalterAndrei.pdf).  Basically it makes the return type of the function 
const or not, according to whether a particular parameter (e.g. 'this') 
is const or not.
