Error when compiling module with "--strict"

[lucch]

I was trying Fay and wrote the simple following program:

{-# LANGUAGE EmptyDataDecls #-}

module Hello where

main :: Fay ()
main = do
    putStrLn "Hello Fay!"

After compiling with fay Hello.hs --strict Hello and loading the HTML in the browser, I get the following error:

When I remove the main function, the TypeError message goes way. Despite of that error, I noticed that it's still possible to call Fay functions from Javascript: I added the following functions to the Hello.hs file:

myAdd :: Int -> Int -> Int
myAdd x y = x + y

myAddCurried :: Int -> Int -> Int
myAddCurried = (+)

What is intriguing me is the output of myAddCurried. What does that mean? Am I doing something silly?
