Inspectopedia Help

Multiple operators with different precedence

Reports binary expressions that consist of different operators without parentheses.

Such expressions can be less readable due to different precedence rules of operators.

Example:

fun foo(b: Boolean?, i: Int?) { val x = b ?: i == null // evaluated as `(b ?: i) == null` val y = i ?: 0 + 1 // evaluated as `i ?: (0 + 1)` }
