That is one thing that rdmd does (as I mentioned in the original
post).
I just looked through the rdmd code
(https://github.com/dlang/tools/blob/master/rdmd.d) and it looks
like it invokes the compiler using "dmd -v" to get the list of
modules and then invokes the compiler again with the modules it
found to perform the full compile. So my original thought that
the logic to find modules is duplicated was incorrect. Instead
we just pay a performance hit to get the correct list of imports
since running "dmd -v" seems to take almost as long as the actual
compile itself. So this method comes close to doubling the time
it takes to compile than if the feature was implemented in the
compiler itself.
In any case, the idea is to allow the compiler to resolve this on
it's own without help from rdmd. This would remove the need to
invoke the compiler twice, once to find the imports and once to
compile. It would also allow some projects/applications that
don't use rdmd to take advantage of this feature, this may or may
not include dub (not sure on that one).
