[Haskell-cafe] jhc speed

[Peter Verswyvelen]

Would it be possible to separate the frontend (Haskell to Core) and backend
(Core to machine code) from the Haskell compilers (requiring a standard Core
language?)
I'm not sure how many extensions required a change to the Core language.

Most likely this is nice in theory but hard in practice?
