I don't think I have the breadth of your knowledge, so I would really love any thoughts you had on the language/OS I'm creating, github.com/civboot/fngi.

It's partly inspired from Oberon (although I started it without knowing about Oberon), but I'm still working my way through the book and language as I develop my own. I'm sure it's going to a decade+ project to have something valuable, but I'm hungry for any feedback I can get at this early stage.
