IMO not to have the Elvis operator in D (actually "??" is less 
interesting than the Elvis "?:" because of D automatic 
dereference and also because of boolean eval of stuff like 
integers and classes instances or pointer) is not a huge issue.

Not to have the safe access operator is more a problem. One is 
about having shorter ternary expressions (Elvis), the other is 
about saving sometimes 4 or 5 "&&" with at new "&&" a longer 
unary (Safe access).
