Implementing "instanceof" is in the todo list. I haven't looked into
the details yet. Probably similar to how Java works. Although I have
always found it a bit confusing that it results in true for an object
that is a child of the class being tested with.
I have also been thinking of an alternative of type() that includes the
exact class. So that you could do:
type_ext(object) == type_ext(SomeClass.new())
Similar to typename(), except that it would make a difference between
classes with the same name declared in different scripts. Hmm, perhaps
adding the script number would work? Thus if you define a class MyClass
in script 4 and script 7, you would get:
object<MyClass/4>
object<MyClass/7>
This win't work if a class can be defined more than once in one script
file. E.g. when it's local to a function. An alternative is to give
each encountered class a unique number.
