Thanks for the boost! I'm plugging away at this at a rate of ~half an hour first thing in the morning; and sadly I am not a morning type. So it will be a while before there is anything tangible.

@wim_v12e I'm not in a hurry, I've just installed f90 on my machine.

I love the design notes you've written, I think I understand what you're trying to do.

Most of the challenge arises from the need to create sets and associative arrays that are compact and can easily be limited in size. It means there is a lot of indirection in the code. But I am slowly getting there, also in terms of the semantics. The SPEC.md is meant to be understandable for other people but the design sketches are just might thoughts as they occur to me, they are not even internally consistent. Thanks for reading!

@wim_v12e well if you have any question, or have issues with implementation, let me know I'll be happy to help 😀

Thanks a lot! I think I might when I get to the code generation stage. Right now I am in the "total mess" stage ^_^
