If you say that whatever data is put there doesn't matter at all, the one thing you definitely cannot ever do later is give it meaning.

Unless I say it's meaning is to be optionally reflected upon during runtime!

Look, I understand the purism and mostly, I agree. But this is not a clean slate language, it will never be perfect and it's going to become more and more idiosyncratic as times go by.

I don't see how it's optional.

Comments are a kind of freedom in code. You're completely free to use them precisely because (in a plain execution environment) they cannot influence the result of evaluation

If comments /can/ change the result of evaluation then you simply are not (completely) free to use them. (And yes I know that this is a simplification in JS where you can already get the source code of a function with toString... Ugh)

Makes sense. I'm excited for your solution, despite not having seen it. If you can solve that, it would be awesome.
