Using ``++Collection.size()++`` to test for emptiness works, but using ``++Collection.isEmpty()++`` makes the code more readable and can be more performant. The time complexity of any ``++isEmpty()++`` method implementation should be ``++O(1)++`` whereas some implementations of ``++size()++`` can be ``++O(n)++``.
