The closest thing to that is to use [https://github.com/timholy/Revise.jl](https://github.com/timholy/Revise.jl). It doesn’t fix the problem that Julia doesn’t cache native code between Julia sessions, but it does allow you to change code and use it without restarting Julia (while only recompiling what needs to be recompiled), which can be a massive productivity boost.
