I'm writing proof-of-concept applications in it for our company currently. Our core technology is Erlang (and Elixir), so the jump isn't comparatively as ridiculous as a Java shop suddenly writing PureScript on the BEAM. I trust code written in PureScript far more than I do code written in Elixir and there are already at least 2 companies using `purerl` in production with the majority of their code in PureScript.

With that said, I've been writing Elixir since 2015 and have worked with Erlang & Elixir since a couple of years after that (+ Haskell), so I'm both much more likely to use niche languages and I'm also well versed in using the BEAM. PureScript with `purerl` actually matches Erlang much better than Elixir does, since Elixir spends half the language and standard library trying to not be Erlang, so I find that it's a better match than Elixir even as a citizen of the BEAM, and the type safety is something I've wanted on the BEAM since I first wrote production BEAM code.

All in all I've been blown away by how solid `purerl` is. The runtime is Erlang, the language is excellent; it's what I dreamed about Haskell being but couldn't quite get.
