I think that's exactly the concern he's voicing.

Limitations of the separate compilation model have come up before. For 
example, the inability to retrieve all the subclasses of a base class. 
Pretty sure there's been others, too.

Since whole-program-at-once *is* a common way to use D, I've always felt 
that (issues of manpower aside, of course) whole-program-at-once users 
shouldn't necessarily be robbed of abilities just because *other* 
projects can't use them due to their own usage of separate-compilation. 
Sometimes things are mutually exclusive. Doesn't mean we can't let the 
user choose their tradeoffs for themselves.

But that's kinda venturing off onto a tangent.
