Comment From: jreback
actually in theory these could be an engine (parsing and evaluation)
Comment From: cpcloud
Hmm intriguing. I wonder if having any engine able to use any parser would be a worthwhile endeavor, where if only an engine is provided the engine is the parser.
Comment From: cpcloud
It would be so cool if we could have an intermediate language that all engines would accept. Hm Python byte code? I suppose that ultimately is what happens wonder how difficult it would be to use it

Anyway that's for another time. Don't want to hijack

None of those listed projects have seen activity the last year, so closing this. If somebody cares about them, of course still welcome to add them to the ecosystem page, but we don't need an open issue for it :)
