Our talks at JuliaCon have been on how to use Julia for systems programming (eg https://www.youtube.com/watch?v=AaQ7XuAR2yY ), which is not an obvious thing you would do.
We sponsored JuliaCon 2018/2019 and work with Julia Computing to fund improvements to Julia.
Let me know if you have any questions!
Additionally, a lot of use cases were discussed at the recent JuliaCon (and in years past): https://www.youtube.com/user/JuliaLanguage/videos
There is also now PackageCompiler that provides a nicer API without requiring you to build from source: https://github.com/JuliaLang/PackageCompiler.jl
I've tried doing these algorithms in other languages (Swift, Rust, C, Python), all of them were getting in the way. Julia is really liberating, I feel like I can concentrate on the hard parts as opposed to fighting the language.
You hit the nail on the head. This is exactly what I do in many of my workflows. Fortunately, Julia is so good on its own that I don't have to do this very often. I can't wait until static compilation is done!
