Ah, that makes sense. So I tried with the latest 0.5 nightly and I go from ~3ms to ~1ms, a nice improvement! (different than what Andrew reported above, so perhaps something changed over the last few nights tho) Unfortunately ProfileView is giving me an error on 0.5, but from printing the profile data I can at least confirm jl_apply_generic is no longer being called.
