Could anyone summarize how well PureScript and Elm treat sourcemaps/debugging in the browser? For a while I thought that js_of_ocaml didn't support sourcemaps, but it turns out, one of my dependencies wasn't compiled with debug flag (-g) and I was able to get a pretty good sourcemaps/debugging experience in Chrome dev tools once I fixed that issue. Is there something js_of_ocaml can learn from PureScript/Elm's JS compilation toolchain? Or should we look to CLJS (which I'm also really excited about) as the best example?
