You don't want Nil there; it's not the undefined value, it's a value of a
special type. You want Str, the type object for Strings, which also serves
as the undefined value (also true for other types). You can test it with
`defined`.
$myObject = MyClass.new(Str);
then you can test $!value.defined or whatever.
