Is there a way to combine interfaces into a single file? If I have modules A and B, I want to create a module C with all the exported definitions of A and B such that I can compile against C.hi file without needing the A.hi and B.hi files. I tried this: module C (module A,module B) where { import A; import B; } ...but if I attempt to compile against C.hi using definitions from A and B, GHC complains if I don't have A.hi and B.hi. I want C.hi to contain everything that A.hi and B.hi do. -- Ashley Yakeley, Seattle WA
