What's frustrating about your analyses is they fail to mention or account for 
any features D has that make it more reliable than Ada. It's like you took a 
list of Ada features and ticked off which ones were not in D, thus making it a 
foregone conclusion that D can never be more than a pathetic subset of Ada.

For once I'd like you to take a list of D features and tick off those not in Ada 
(or whatever other language du jour).

Like transitive immutability.
