runghc -fdefer-type-errors

[Kazu Yamamoto ( 山本和彦 )]

Hello,

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.
