Gren is a fork, not a spiritual successor. And not only did it not fix that problem, it made it worse: https://news.ycombinator.com/item?id=36275171

Yeah, I just read this further down in this topic. Really bummed about it, Elm always seemed so promising, and I thought a healthy fork was what was needed.

I just don’t understand the reasoning for this choice.

Perhaps because it's not the big problem a few people make it out to be..

along those lines, Zokka is a fork of elm that appears to be mostly dedicated towards bug fixes that Evan (the creator of elm) refuses to acknowledge or merge.

edit: there's also Roc, https://www.roc-lang.org/, a language started by Richard Feldman who I believe was a former elm core team member. I think Roc aims to accomplish different things than elm, but definitely feels like a spiritual successor

The commitment to bidirectional compatibility means that Zokka can't fix the problem that GGP was talking about.
