var and Atomic

[rewlad]

Why is it written var counter = AtomicInteger()?
It seems to be val, because counter itself is not mutated, but the value of atomic does.
And this way we leave someone possibility to do counter = in an unsafe way.
And we can not make CI rule to warn of unsafe global mutable state.
On the other hand may be someone (who does not know what is Atomic*) needs to see, that counter has mutable meaning.

That's a bug. Thanks for noticing!
