Keep your julia session open and use Revise.jl (maybe even with [this](https://discourse.julialang.org/t/scripting-like-a-julian/50707) workflow?) instead of restarting julia over and over. Another option would be Pluto.jl.

I don’t know how your script is written, but if it’s not in the form of functions without globals, chances are you’re leaving a lot of performance on the table anyway, regardless of restarting julia or not.

The first part of this already works if you put your code in a project (which is used to manage dependencies). The second part about not having to recompile the code is not currently possible, but may be possible in the future.
