I mean, aren’t you just describing formal language syntax? Seems like a fundamentally similar situation —- the computer can automatically flag any syntax errors in a millisecond by checking it against the generating grammar for that language. Thats what makes a formal language in the first place, I think!

I do think this language is considerably more robust than the typical programming language, which means a sound program is more likely to end up being valid/“correct”. But still, that’s a difference of degree, not kind, IMO
