I think we should try to avoid using newlines in these notes.

Okay, I'll change them all to other punctuation.
What's the problem with newlines though?
The console output will already have newlines from snippets, and the json output is all string-escaped.

I agree with @externl on the new lines in the error descriptions. Do we do this anywhere else?

There's a few scattered around notes and error messages.
Just whenever something seemed more readable on two lines.

This PR implements #681 by adding support for compact enums.
Compact enums work just like compact structs: we don't encode
TagEndMarker, and tags cannot be used within the enum.A compact enum cannot have an underlying type (since they're already 'compact') nor can it be unchecked (since we already don't encode
TagEndMarkerthen).
