Explicit 'get' or 'set' call

Reports explicit calls to get or set functions which can be replaced by an indexing operator [].

Kotlin allows custom implementations for the predefined set of operators on types. To overload an operator, you can mark the corresponding function with the operator modifier:

operator fun get(index: Int) {}
operator fun set(index: Int, value: Int) {}

The functions above correspond to the indexing operator.

Example:

class Test {
    operator fun get(i: Int): Int = 0
}

fun test() {
    Test().get(0) // replaceable 'get()'
}

After the quick-fix is applied:

class Test {
    operator fun get(i: Int): Int = 0
}

fun test() {
    Test()[0]
}
