An unordered pair is easy to handle, but the longer an unordered set gets, the harder it is to deal with.
This rule raises an issue when a tuple of more than the allowed number of elements is returned.
Noncompliant code example
With the default threshold of 2
func doTheThing() -> (Int, Int, Int) {} // Noncompliant
Compliant solution
func doTheThing() -> MyIntStruct {}
