List find method finds nothing, but let is called (?!)
i have the following code:
myList { it.code == item.bin }.let {
// 1

} ?: run {
// 2

}

I would expect that, if item is found, I enter block 1 , otherwise block 2 ;
But instead I enter block 1 in all cases, and if nothing is found , it is null
Android studio seems aware of this, as the block 2 is grey (it is code never called), but I can't figure why
Please may someone explain why ?
