Once that key language feature is added, then your particular use case of HASH as the backing store can be wired up with a few lines of IDL code, and you can choose whatever idiosyncracies you wish.

Hi Craig,
Actually, it is already overloadable. As long as your class inherits from IDL_Object, then using a "." will call GetProperty (if it is on the right-hand-side of the equals), or SetProperty (if it is on the left-hand-side).
And you're right, it was indeed just a couple of lines of code. The trickiness comes in because the IDL parser has already made the "field" name uppercase by the time it reaches the internal C structure code. I really don't want to mess with the IDL parser.
