You do know, that you already *can* have safe Text and ByteString from an overloaded string literal.
Yes, the IsString instances for Text and ByteString are safe (I hope).
But in order to use them, I have to turn on OverloadedStrings. That could cause other string literals in the same module to throw exceptions at run time.

Actually, the ByteString instance is arguably unsafe as well: {-# LANGUAGE OverloadedStrings #-} import qualified Data.ByteString.Char8 as S8 main = S8.putStrLn "שלום" It would be nice if usage of characters outside of the 0-255 range could be caught at compile time. Michael
