Comment (by simonpj):

 I'm not sure which comment you are replying to; and I fear I don't
 understand what "something like this" is.

 The big trouble with recursive modules is that: either you need a
 programmer written signature file (i.e. `.hs-boot`) or you have to compile
 all the modules in the SCC at once.  I don't see any other path.
