Hi!
When writing library code that should work with both String and Text I
find my self repeatedly introducing classes like:
class ToString a where
toString :: a -> String
class ToText a where
toText :: a -> Text
(I use this with newtype wrapped value types backed by Text or
ByteString.)
So I wonder whether it would be a good idea to have a package that
provides those classes.
Or maybe just ToText, and provide default implementations of toString
and toText, like:
class ToText a where
toText :: a -> Text
toText = Text.pack . toString
toString :: a -> String
toString = Text.unpack . toText
How do you guys deal with that? Any thoughts?
Cheers,
Simon
