Currently, it takes more than 2 seconds to load the package `juliacall` in Python, before importing any Julia package or running Julia code: ``` $ time python -c "from juliacall import Main as jl" real 0m2.355s user 0m3.104s sys 0m0.156s ``` This can be a disadvantage compared with calling C++ instead of Julia to offload heavy computations outside Python, depending on the workflow. Is there a way to compile a Julia system image to make the startup much faster?
