 Note this is a work in progress; many types of syntax are not yet handled.
 
 1. You need a 1.13.0-DEV build of Julia: At least 1.13.0-DEV.880. Commit `5ebc5b463ea` is currently known to work. Note that JuliaLowering relies on Julia internals and may be broken on the latest Julia dev version from time to time.

+2. Use commit `e02f29f` of [JuliaSyntax](https://github.com/JuliaLang/JuliaSyntax.jl)
 3. Get the latest version of [JuliaSyntaxFormatter](https://github.com/c42f/JuliaSyntaxFormatter.jl)
 4. Run the demo `include("test/demo.jl")`
