How can you check in Kotlin if two objects are the same instance by reference?

In Kotlin, to check whether two variables refer to the same object in memory, the === operator is used. It checks referential equality, unlike ==, which checks structural equality (calls equals()).

Example:

val a = Any()
val b = a
val c = Any()

println(a === b) // true, because b refers to the same object
println(a === c) // false, different objects
