Yup! Most of the time apps are merely "translated" versions of rails
frontends. (For better or for worse, I assume that if we were to port
haskell to work with Android really it would be mostly to appease my

I'm not sure I understand completely, but I agree this isn't a bad idea.

I don't disagree!

I am venturing into my embarrassing lack of knowledge about GHC
internals here, but how easily would the run time system work on
Android..? I had assumed a large part of the effort into getting
OCaml to work on iPhone went into the runtime system, no?
If you're (Andrew or anyone) still interested in pursuing this I would
be interested in helping out, I have some Android internals knowledge
and would be glad to lend a hand.
One major thing that seems to be necessary is congealing all the
(mis/outdated)information into the wiki article on haskell.org.
