I hear ARM support will be standard in the next GHC, and there currently are ports and cross-compilers. Unless you're specifically talking about ghci, which I agree needs to be ported, though that hasn't happened for the browser yet. It's possible a project like this could help that happen, though...
I am looking to the gchi because it's mainly to play and learn . I think a mobile/tablet is a nice environment to do that.
There are ports of ghc to both Android and IOS. I've run ghc directly on Android. ghci not so much, so you're technically right about there being no interpreter.
That's awesome! I have played a lot with Scala and Android, and type safety, options, futures really improved the development on Android (less code, less bugs).
I would be curious to try Haskell on that platform.
