Ambivalent here. Does it make more sense to have a send :: StringLike s => ... or sendS :: String -> ... sendBS :: ByteString -> ... sendLBS :: L.ByteString -> ...
I've never understood why people want these type classes. Just pick the right one. Each of those types has functions for converting to each other. Let the caller do the conversion if any needs doing, it's just a function call.
Also if we have separate functions we need yet another set of functions when Text is ready.
Which also comes with functions for converting to ByteString or String. Duncan
