Since hearing about it we have a port of a large project in progress and whilst the typing is nice, the improvement in build time alone looks like making it a worthwhile exercise.
Big things to come I suspect, particularly with it feeling like such a natural progression of so much of FB's recent JS work.
Seems like a natural fit. Wasn't the whole Fiber architecture inspired Algebraic Effects, natively possible in OCaml?
Sebastian Markbåge even toyed with adding algebraic effects to JS... wild stuff:

I'd love to see an explicit "percentage of those who've used it who would use it again" number for each library, easily glanceable. I think that's what most of us are probably doing in our heads when looking at this data.
