That's cool! Half way done. :)

I'd tend to use MyArray.Add(Item,Position) to insert items at arbitrary 
positions.

It would be nice to have Shift and Unshift, if nothing else, to improve 
the symmetry of the language:

              [][][][][] <- Push
              [][][][][] -> Pop
   Shift   <- [][][][][]
   Unshift -> [][][][][]

Of course, it's important to consider the impact, in terms of risk and 
performance, of implementing such functions on regular arrays.

What do you think? It's worth the risk? (Considering Gambas already has 
Push() and Pop()...)
