In CoroutineScope(Dispatchers.Main + job) the order of contexts doesn’t matter and it’s the same if I call CoroutineScope(job + Dispatchers.Main), right?

TL;DR Almost, but I suppose it doesn’t matter for end user.

Both Job and CoroutineDispatcher are CoroutineContext and fun operator plus combines them and its subelements.
But if element of context on the right side has same key as the element on the left side, that element with that key of the left side context won’t be used.

Got it, thank you!
