Have body be anything that uses String.Chars

In order to make things as flexible as possible, have the body of a Mail message be anything that implements String.Chars. This lets each message type know how to encode itself, maximizing future extensibility.

I realize this was opened a long time ago, but I'm triaging now. Do you happen to recall your use-case? The message body should always be a binary which does implement String.Chars. Or were you suggesting implementing the prototcol on the message itself?

I think I posited this for implementing MIME and other kinds of message types, but I'm not sure (this was so long ago).

Come to think of it, it might be useful to have another protocol for an email message specifically, but I'm not 100% sure what that looks like.
