At the moment, bindings for Readline and Linenoise are available, which
are mainly used for making the REPL more convenient to use. Editline is
a BSD-licensed alternative to the two that's part of the userland by
default on FreeBSD, OpenBSD, and NetBSD. Having bindings for Editline
would be more convenient for BSD users, since they don't have to install
any additional libraries to use the REPL more comfortably. Would this be
worthwhile writing? It fills a pretty narrow niche for users and I'm not
sure how useful it would be to have.
