and that issue does have nothing to do with the Pi Pico, I believe. Because it applies to PackageCompiler.jl (or full Julia, I’ve never used that option that way though, only as --compile=min, i.e. then interpreting, not compiling), that will likely never support the Pico. Other packages to help compile to 256 RAM computers (or less) do not use --compile (or the runtime), I suppose.
