There sure is a way to call from other languages - cf. "foreign export" -
but don't know how hard it would be to make Haskell live without its "main",
which performs a lot of runtime initialization.
For me (with nhc98) it's a lot easier to use a Haskell "main" that's just
a brief wrapper:
module Main (main) where
import NHC.FFI
foreign import ccall "cmain" cmain :: IO ()
main = cmain
(... where "cmain" is an external entry point in the C code, which can
then call Haskell as required.)
