You posted this before seeing the additional clarifications Mr. 
Davis and I posted, and I understand that, but I just wanted to 
say that factoring what we both said I think it's clear that it 
is really different. Not bulletproof (I'd say const + pure would 
be nearly bulletproof and immutable + pure would truly be 
bulletproof if you started considering multi-threading), but 
certainly better than C++.
