This kind of thing is unfortunate, but I don’t think we need to be too concerned about it. Eventually, the tooling will make this a bit easier, and for now it seems sufficient to me to use these command line flags at the top level for `"Hello, World!"` type scripts and during prototyping, and also module-level options where that makes sense.

I’m currently trying out this idea of launching one script with the flags for setup-type stuff and then calling another julia process without those flags inside. I’ll report back once I’ve worked out the kinks 🙂

Can Jupyter kernel be started with these options as well? How?

You can use [Installation · IJulia](https://julialang.github.io/IJulia.jl/stable/manual/installation/#Installing-additional-Julia-kernels) but then it would run without optimizations and inference.
