Thanks kbenson!

I love to learn new techniques from our dev community.

Note that the technique of doing "dynamic dispatch" with the associative array syntax:

c["func"]() 

will only work if the underlying object is an associative array. This is not true for objects created with the CreateObject() function. This technique will not work with those objects, and you are back to using Run() or eval()

I suspected as much, but hadn't bothered to test. Luckily, that can be solved through a simple wrapper class that just dispatches to the component methods. Obviously there will by a little overhead (probably negligible unless there's LOTS of calls), but also the ability to put in sane defaults to the common use cases. In all, a fair trade-off in my opinion.

I know it's a long shot, and there's other stuff to work on that's more important, but closures would be really useful right about now. Are there any scheduled plans for them in the future, or is it still a "it's possible" thing? Anonymous functions are great, but anonymous functions with closures are awesome.

There are no immediate plans to provide closures in the language. I agree they would be useful.
