Can't you just use "=nil" to achive the same thing?
(just using the fact that 'nil' is false)

in perl it's null. which is what defined() and undef() test for...

In ruby, you can *always* do:

foo.nil?

This will return true or false. Similarly, you can also test for
.empty? (-> true) on a lot of containers, etc.
