Doesn't runghc support the -fdefer-type-errors option?
Consider this code:
module Main where
main :: IO ()
main = do
-- putStrLn は文字列を取る
putStrLn "Hello, world!"
putStrLn 1 -- 型エラー
If I use runghc with -fdefer-type-errors, "Hello, world!" is not
printed. Is this a bug?
If this behavior is intended, I would like to change it. If GHC can
run code like dynamically typed languages, it would be appealing to
new Haskell programmers from their community.
