Re: FFI, safe vs unsafe

Hi

- we've been told here that concurrency is just a library No, its not. The interface to concurrency is just a library, but internally certain things in the runtime have to change.

- FFI allows other Haskell' implementations to import that library If all Haskell' prime implementations depend on "GHC the library", then do we really have many Haskell' prime implementations, or just a pile of wrappers around GHC?

Thanks Neil
