As discussed earlier, using ":var" / ":final" / ":const" looks like a
much better way to declare variables and constants. It diverts from
what TypeScript is doing, but gets closer to some other popular
languages, such as using "final" as in Java. And avoids the
Vim-specific use of ":const!".
I'll keep using ":let" as an alternative to ":var" for a little while,
so that those who already started using Vim9 syntax have a chance to
update their scritps. Let me change that a week from now.
I'm going to change more tests so that we get a feeling of what we end
up with. Feel free to discuss alternatives.
