The array operators are missing on this list. They are probably important?

https://github.com/querycert/qcert/blob/wasm/compiler/core/EJson/Operators/EJsonRuntimeOperators.v#L48-L51

RuntimeArray is n-ary and the n is not known locally. I need to know the n for compilation.

Just updated the list to reflect the latest state. Also added the non-runtime operators.

I made some progress in 9578251.
I think implementing and debugging the runtime would benefit from a set of unit tests per operator. How would you do it? My current best guess is to add Imp tests per operator under /tests/operators/<operatorName>.imp_ejson. Or do you have something like this already?

hm. that's a really good question. And no, we don't have anything of the kind even for JS. This would be super great though.

I think one question is whether those tests are written in imp_ejson or are they written against the runtime itself (i.e., in JS, AssemblyScript).
