That does bring up one thing I think he might like about D versus C++: C++ 
tends to leave a *lot* as undefined, whereas D tries to avoid doing that. I 
have no idea if that applies to virual table implementations, though.

Although, if he suddenly decided he wanted to change something about the 
implementation of virtual tables, with C he'd probably have to rewrite a lot 
of code. Not so with a "depends on the implementation" form of virtual 
tables. But maybe he does have it abstracted away with macros of something, 
I dunno. Heck, I might not even be making any sense anyway, it's bedtime and 
I'm about half asleep already...
