I think I've heard you state that before.  Can you be more specific?  What
alternate system do you have in mind?  Is this just wishful thinking?

That's true, but without static typing don't you have to treat them as if
they did?  At the very least you need to do a "is it an object with a
DESTROY" check at block boundaries.

2x the penalty, right?  Instead of a speed increase we carry the burden of
ref-counting in addition to the overhead of an alternate system.
