It would be highly ironic if you consider to buy a superfast computer for the high-performance language Julia, because it’s slow at compiling!
With my trick for faster recompilation, I seem to have converted one Common Lip user to use Julia: not-common-lisp-to-julia.org · GitHub
You can have 20 KB Julia executables, but those are limited (e.g. no GC), with Python most or all of the important limitations are lifted (StaticCompiler.jl doesn’t yet support Windows, so I’m not sure this works there, even if you use Python for the Windows compatibility):
I hope my PlotlyLight.jl suggestion helped, any plotting library (and more code) is likely excluded with that approach though, but if you do the plotting from the Python side, then something similar is I guess available.
