[Haskell] (GHC) Boot files and instance declarations

[Simon Peyton-Jones]

At the moment GHC just doesn't support this, I'm afraid.  It's a
shortcoming, and one that could be fixed, but not in a minute or two.
You'll have to find some other way to reorganise your code, I think.

Incidentally questions specific to GHC belong on ghc-users, to which I
have redirected this message

| Hi all. A quick bootfiles question.
| 
| The GHC docs specify not to put instance decls in bootfiles. However,
| what if i need to? For example, say I have a module A where I'm
| importing a module B with the {-# SOURCE #-} pragma. Module A needs to
| know that the types in module B are instances of some typeclasses
| (instance declarations for which are given in module B). How would I
| manage this?
| 
| Thanks in advance.
