> The one you need is this which is already merged but was after the 1.10 feature freeze so it has to wait till 1.11, though you can test it with nightly builds which is available on julialang site: https://github.com/JuliaLang/julia/pull/51435

The discussion seems to be too deep in Julia internals for me to follow. Is this about startup time or defining an entry point (or both?). I haven't had problems with Julia entrypoints (yet at least).

With the nightly `./julia-f7618602d4/bin/julia -e "using DynamicalSystems"` still takes over 5 seconds. Can I somehow define a main to make this faster or precompile more efficiently?

Sounds promising. Shared libraries are not a musthave for me, but could allow Julia save us from C++ in more cases.
