FYI, it is by the same people who initiated the Modelica effort (Hilding Elmqvist and Martin Otter). I think part of the goal was to shed having to maintain a whole language (and the need to specify all the semantics details of such) and simply leverage a language that had macros.

I haven't really heard many updates on this in some time. I don't think it is necessarily a bad idea. But any effort along these lines takes a lot of dedicated people quite a while to make progress (as was the case with Modelica).

Thanks for pointing this out, I hadn't realized! I knew they were somehow involved in the Modelica community but not that they initiated it.

That looks really promising.

But development seems to have completely stopped earlier this year. Anybody knows what's going on there?
