After a list filter, I have to cast it to the filtered type, like

Copy code

list.filter { it is A }.forEachIndexed { index, item -> (item as A)

Is there any way to smartcast it?

Use

.filterIsInstance<A>()

extension instead

there is an issue to provide Koltin IDE plugin inspection to replace such cases with filterIsInstance()
