Combining Module Interfaces

[Simon Peyton-Jones]

No, GHC just does not support this.  GHC tries to avoid duplicating=20
information (which might become inconsistent with catastrophic results),

so C.hi simply records the dependency on A.hi and B.hi.
You must have both of the latter available.

| 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=20

| without needing the A.hi and B.hi files.
|=20
| I tried this:
|=20
| module C (module A,module B) where
|      {
|      import A;
|      import B;
|      }
|=20
| ...but if I attempt to compile against C.hi using definitions=20
| from A and=20
| B, GHC complains if I don't have A.hi and B.hi. I want C.hi=20
| to contain=20
| everything that A.hi and B.hi do.
