I figured the eager ones wouldn't be a problem, but I wondered whether 
the lazy ones might be a pain.  Guess not, so cool. :)

That's very true...I'm looking forward to Andrei's book, but I can't 
imagine how he's finishing it on schedule, considering how quickly both 
the language itself and the compiler are evolving.  If the language 
specification and reference compiler are both as incomplete, volatile, 
and partially implemented as they are now, a June release might do some 
real damage to D's reputation.

As far as D3 goes though:  Obviously nothing about it has really been 
discussed at length, but is the general idea that it would be another 
backwards-incompatible overhaul, or is the plan to make D2 the target 
for backwards compatibility from here on out?
