break and continue keywords always apply to the real loops (for, while, do-while). break and continue never apply to any function; for example, break and continue don't apply to forEach, filter, map.

Using break or continue inside a loop-like function (for example, forEach) may be confusing. The inspection suggests adding a label to clarify to which statement break or continue applies to.

Since Kotlin doesn't have a concept of loop-like functions, the inspection uses the heuristic. It assumes that functions that don't have one of callsInPlace(EXACTLY_ONCE) or callsInPlace(AT_LEAST_ONCE) contracts are loop-like functions.

Example:

    for (file in files) {
        file.readLines().forEach { line ->
            if (line == commentMarkerLine) continue
            println(line)
        }
    }

The quick-fix adds clarifying labels:

    loop@ for (file in files) {
        file.readLines().forEach { line ->
            if (line == commentMarkerLine) continue@loop
            println(line)
        }
    }
