Yeah, that's quite reasonable.

Thanks; I think I'll wait -- I'm actually quite satisfied with the
current possibilities (Emacs native sexp handling + Paredit and
occasionally the example stuff from pre-merge vimpulse-modal). Nice to

though.

Hm... do you mean you're going to (try to) improve Viper itself? Sounds
great, good luck (I'm serious)!
