Small bugs overall, some of which the team already addressed. One Clojure specific that is outstanding is that dynamic variables are not rebound between electric and Clojure functions. Also, the compiler currently does not optimize the callstack so the whole app stream-renders in and out which has a cascading effect. None of these are deal breakers for me, they're being worked on and I'm glad the community can now help ship fixes and improvements.
(founder here) Thank you Dennis! All, broadly, to date we've focused on achieving correct program semantics over syntax/perf/ux/dx. We're rotating onto these issues now, since we've reached a point where, after 2 years of hardcore dogfooding and 8 months of private beta, we're comfortable that brave Clojurists like Dennis will be successful and have an acceptable development experience. (Especially when compared with the benefit of strong composition at the system level - functional programming over entire systems!)
