valuerunText :: (forall s. (MArray s -> Int -> ST s Text) -> ST s Text) -> Text

valuespan_ :: (Char -> Bool) -> Text -> (# Text, Text #)

valuespanAscii_ :: (Word8 -> Bool) -> Text -> (# Text, Text #)

For the sake of performance this function does not check that a char is in ASCII range; it is a responsibility of p.
