is there any better option than Collections.synchronizedList(mutableListOf()) in stdlib or in libraries ?
i would feel a lot safer if i knew that i do not have any nasty ConcurrentCoModificationExceptions waiting for me due to forgetting to synchronize() on the list somewhere

what is your use case for this?
Usually with coroutines you can replace such mutable structure with actor that allows synchronise operations to mutable state
or use some another approach

@Nikky You might find CopyOnWriteArrayList Useful. But it is costly if you are doing a lot of mutations.

Well.. I am iterating over, filtering, calling contains and adding to a MutableList<String>
I know how to use channels to synchronize adding.. I am not too sure about the rest

You can use actors, it allows you to encapsulate state and safely update it (actor by default process commands sequentially)
