Since a mismatching object.d causes rather ungraceful failures, this was 
done originally to avoid conflicts with other compilers if users were to 
unwittingly install them in the same prefix. Of course, since we 
(unfortunately) have a small set of patches to druntime/Phobos, it would 
still not be advisable to do so even with .object out of the picture.

I would suppose that adding the other path is the better option right 
now – even if we were to condense the two import directories back into 
one, you'd have to wait a year or so unless you can be reasonably 
certain that the change has percolated to user machines.

So it was done under the assumption that these two compilers
installed in the same prefix share the same Phobos version.
Oh well, ok. :)

The libraries are named differently:  `libphobos2-ldc.a` for 
example.
(but you could be right that the phobos _version_ is the same ;-)

Hmm, sorry, indeed the source of phobos would then still be 
shared... doh!

There is probably no good justification at this point anymore, as the 
druntime/Phobos headers would usually be slightly different even between 
e.g. DMD and LDC of the same version. I am pretty sure that the reason 
for the second import path to be added/object.d(i) to be moved was to 
avoid frequent conflicts due to user mistakes, but maybe that was just 
because back then we would crash, or because there was a configuration 
during the D1 days where this made sense. We could probably just move it 
back to the top level now…
