I would vote against it. This may only confuse your code and invite errors
further down the line. Faster CPU's are allways around the corner.

Actually I do have a class OBJ which almost any object inherits. It has three
main methods:

pro obj::debug -- just stops and allows the user to examine the object
pro obj::property -- sets a property (but must be completely typed)
function obj::property -- retrieves a property (same restriction as above)

It in addition has a usefull field like self.version, and I hope to add in
a generic ::read and ::write methods for file access (but I have not thought
that one through completely).

oh, and btw, I've generated up to 0.5MO (mega objects) and IDL was performing
fine. These were instances of incorrect cleanups, but I was still glad
nothing got corrupted.
