I hope so. Between you writing a one-hundred lines class and me having 
to rewrite the IDE, the components, and my job's big project, the choice 
was fast. :-)

I think it would be possible even if it is some work.

I would have to assume that:

- If there is a _get() method that takes an integer, and if there is a 
Count property, then I can display the object like an array.

- If there is a _get() method that takes a string, if there is a Count 
property, and if there is a Keys property that returns all keys in the 
object, OR both a _next() method and a Key property that returns the key 
of the last read value, then I can display the object like a collection.

What do you think about that?
