Comment (by FPtje):

 Shouldn't the -i problem you mention be resolved simply by giving those
 folder the highest priority?

 Standard behaviour for lots of compilers and interpreters? Haskell is a
 different language altogether. Rules from other compilers do not
 necesarily apply. The extra search paths aren't "clever magic", just an
 extra place to look for modules. It doesn't have to make anything more
 complicated.

 Finding wrong modules shouldn't happen, at least not in the example you
 provided. Especially when -i paths have priority over the other paths.
