This looks great. Some takeaways from looking into the documentation: They're promising 10x - 100x better performance (since vim9script is typed and will be compiled). Also -- you can mix vimscript and vim9script in a function, a file, or a module. This will let legacy modules or scripts stay mostly the same but port some of the slower-running bits to vim9script to gain the benefits without a giant effort to port the whole thing.
