Hey,
GHC seems to have a very powerful core language, which makes implementing language features less painful. As further applications of Core were mentioned: let other languages use it and build new features upon it.
Here's a silly idea: Would it be possible to use Haskell and Core in parallel, in the same module or at least in the same program? Can Core integrate smoothly with Haskell?
The benifitz of such feature would at least be:
* Easy implementation and testing of new language features * Use language features that are used too seldom to justify an implementation in haskell * Some code may be easier to implement/understand, when it is in core form
GHC has a feature that theoretically allows you to link .hcr files along with .hs files; the External Core system. It has been broken since 6.0, but Aaron Tomb et al are busy fixing it, and it is expected to be usable this year. Stefan
