Even after the first time symbols have a non-trivial cognitive cost for a lot of people, if not most, all while providing near zero benefit unless your app is pretty much nothing but a bunch of inline json expansions.
Because * / - + is the common ground that essentially everyone is familiar with. And that's about as much math notation as makes sense in general purpose programming languages.
There is only one math but many programming languages. Multiplication is universal and fundamental. Creating JSON objects in nim is the opposite of that.
If I entered "nim json" into google I'd get thousands of results for the language and json in general, and no way to narrow it down to meaning the operator "JON". That's not really what searchable means.
My google insider tells me you can add the word "operator" to your query to do that. Or any other similar word like "keyword" that anyone else thought to call it on stack overflow.
