Comment (by duncan):

 Thanks to Stephen we've got this one done finally.

 You can now have executables specify `build-depends` on the library in the
 same package. You must specify `cabal-version: >= 1.8` to use this
 feature. Note that the executable must not specify the same `hs-src-dirs`
 as the library or it'll just pick up the source files rather than using
 the built library.


   * Add a QA check to make sure people are not specifying internal deps
 without using `cabal-version: >= 1.8`
   * Update the user guide to explain the feature and restrictions.
