> you convert String or Text: what encoding would you use?

let's say, this is very specific conversion where newtypes are used a
lot. There are many different formats for Int (even the same type of
int), String may be ascii, UTF8, ISO-..., you name it.

using class does not make a difference re: type definition in this case.
