I assume you're talking about this:

I guess, "difficult to figure" means that the notorious 
sufficiently smart compiler is unrealistic. Too bad, because I 
don't like the idea of adding verbosity (auto ref) for the common 
case. pure and @safe already have that flaw, and I'd rather see 
no more semi-compulsory keywords.
