And Objective-C, in which calling methods on (er, sending 
messages to) null references is not only allowed, it's just good 
manners.  Coming to D from that was a bit of a shock with the 
sudden segfaults, though eventually we adapt.  Still, it would be 
nice to have the option of Errors thrown rather than a straight 
crash.  I assume this is for efficiency reasons, but couldn't a 
compiler flag be a consideration?  Debuggers are nice but it's 
still an extra, external step.
