@frescosecco tangential, but wasn't there a project long ago to make an Emacs clone in Erlang? SWI-Prolog has a barebones Emacs clone! An Erlang Emacs makes a lot of sense when considering that Emacs became more usable after it got async support. If parantheses matter, there are multiple Lisps on the BEAM.
@tetrislife I wasn't aware of it; there seem to be traces of an old project called Ermacs. Thanks.
