did you know you didn't have to use actual objects to implement object-like behaviour.
this has the effect that you can extend the object at will...

I have no ideas about speed, just that this could be a solution to your problem
example:

New version 0.18 of DyBASE Rebol API is available.
Now it is not necessary to specify prototype object: DyBASE is able
to fetch object with arbitrary set of fields. It is possible because
now fetching of object is done in three steps:
1. Fetch object fields into the block
2. Create object using

Which word do you want to protect? close?

I'll just add some comments.
