create compiler frameworks for new compilers about cabal HOT 2 CLOSED

(Imported comment by @dcoutts on 2006-01-20)

The Compiler abstraction should certainly be beefed up. I'm not sure we need to go as far as making a external serialised form.

Currently the Compiler value is passed around but is used as a bit of dumb data when it should really carry methods for doing interesting things and we should not be switching on the CompilerFlavour. The difficulty with doing this is that currently the Compiler value is passed around using the LocalBuildInfo which implements Show. We should really pass Compiler as a parameter but we cannot do that without changing the type signatures of the UserHooks which would break all custom Setup script again.

So we have to synchronise this change with our next planned break of UserHooks. Ideally that break should include a plan for an api style that does not involve so many breaks when we want to pass just a bit more info, like using some kind of monad where we can extend the environment without breaking existing code.

Doesn't seem like there is activity on this since 2006. I propose closing, please re-open a new issue if this is still desired.
