I'm not familiar with automatic cabal flags. Could you point me to
documentation?

Is there any way to determine whether Integer comes from integer-gmp or integer-simple? I'm playing with the idea of using the underlying representation to get more compact/efficient tries, but I need to be able to find out what that representation is. One way could be to use an automatic cabal flag. With it enabled, depend on integer-gmp and add hs-source-dirs to a directory containing your integer-gmp implementation, with it disabled, depend on integer-simple and add hs-source dirs to a directory containing your integer-simple implementation. This gives module-level control. With automatic flag I think cabal will try both and choose the setting that gives the best build plan (likely corresponding to the Integer implementation of your ghc).
