C4Script: function IsRef() returns always false

[Somebodyisnobody]

The function isRef() returns always false since 2017 or 2018 according to @maxmitti. Opening an issue that it can be tracked.

It’s probably broken for much longer already. I’m just aware of it since then.

Is anybody working on this issue? If not, I'll give it a try.

I think nobody is working on it. The question is if we want to fix it.
If it suddenly starts working, old code could change behavior, which we don’t want for compatibility reasons.

Furthermore, it is not as trivial as just adjusting the implementation of the engine function, because in LC’s C4Script there is no such thing as optional references.
Either an argument must be a reference and it is an error if it is not, or it doesn’t take a reference and it will only get a copy.
