Old description:
The ability to build custom runtimes would be useful in many development
situations. Like Objective Caml's -custom, one would be able to create a
interactive-invokable (GHCi) with a custom main () initialization and
finalizer. For things such as SDL applications, Cocoa applications, there
is a need for custom run loops as well. This would be an immensely great
integration feature for GHC. In these situations it is not possible to
work in GHCi on most/all platforms without much work done in a
specialized hs-plugins REPL environment.
Ideas of Requirements:
- specifiable initializer (from main)
- specifiable finalizer
- specifiable run loop / event handler (light thread) as such:
REPL
thread 0 - read, eval (send to thread 1), print, loop
thread 1 - processing events run loop, check for eval + send result to
print stage

Comment:
I'm a bit unclear on what exactly is wanted here. Does GHC-as-a-library
provide it?
