Write concept code

[voltrevo]

ValueScript has a variety of concept code in concept-code.

This is code that (at least when it was written), didn't work.

The idea is to be extremely specific about the future intentions of ValueScript by documenting actual programs and what they should do. As much as possible, they should not be abbreviated - they should be written exactly as they are intended to be consumed by the toolchain.

If you feel you understand what ValueScript is trying to do, or have read about a planned feature that doesn't yet have any concept code, then we'd love for you to contribute some concept code. If accepted, the goal¹ will be for that code to work as you describe with little-to-no modifications in a future version of ValueScript.

Unlike most other good-first-issues, there's a lot of scope to go deep here. Simple concept code is good too, of course.

¹ Not 100% true - if the concept code is particularly speculative it may have lower expectation of being implemented (but still be valuable food for thought)
