Builtin support for nested comments or a canonical way to handle them #133

Open vmchale opened 5 years ago

vmchale commented 5 years ago

Currently, I use an approach here, which is as far as I can tell the correct way to implement nested comments.

I'd also like to keep annotations which are kept in nested comments, which I imagine is possible but isn't straightforward to me. Ether a canonical example or builtin support would be wonderful.

Thanks!
