One thing I do not understand. Once module A, which contains the 
new traits, is compiled using separate compilation, the list of 
found modules is fixed. If now new module B is added, nothing 
will cause a rebuild of A and therefore the list of found modules 
is incomplete.

This can of course be solved by telling the user to not use 
separate compilation, which might be a fair tradeoff, I am not 
sure.

Kind regards
