Issues, off the top of my head: figuring out which is which in 
the first place,  separate compilation causing multiple modules 
to pull in different versions of the same symbols, run-time 
linking hell when external libraries are added to the mix, and 
library bloat when different projects depend on different 
versions.  I'm reasonably certain there are other things too.

It _might_ be possible to do sanely if this had all been worked 
out from the outset for D/D2, but I'm not at all confident that 
it's possible to retrofit (rather, I expect it isn't).
