A set with one element should not be represented as a HashSetCollision1. If there is only one element, there can not be a collision, right?
In the example below, y should be an instance of HashSet1 instead of HashSetCollision1.
// generate hash set with a hash collision
val a = 0L
val b = 1L + (1L<<32) // Long.hashCode is just lsw xor msw
val x = HashSet(a, b)
// remove one element
val y = x - b
// resulting set is a HashSetCollision1 with one element. Huh?
println(y + " " + y.getClass) // Set(0) class scala.collection.immutable.HashSet$HashSetCollision1
