Definitely don't do that. IMHO, "== null and "!= null" should be
illegal. If you really want to check for null, then you need to
use "is null" or "!is null", whereas if you want to check that an
array is empty, check its length or call empty. By using "==
null" or "!= null", you tend to give the false impression that
you're checking whether the object or array is null - which is
not what you're actually doing.
