/**
* A Set is a Collection that contains no duplicate elements.
*
* Great care must be exercised if mutable objects are used as set elements.
* The behavior of a Set is not specified if the value of an object is changed in a manner
* that affects equals comparisons while the object is an element in the set.
* Example usage:
* ``` php
* $foo = new \My\Foo();
* $set = new Set(\My\Foo::class);
* $set->add($foo); // returns TRUE, the element don't exists
* $set->add($foo); // returns FALSE, the element already exists
* $bar = new \My\Foo();
* $set->add($bar); // returns TRUE, $bar !== $foo
* ```
