Oh, you mean cases like doing a #perform:withArguments: where the VM
relies on certain object representations (e.g., the first argument must
be a Symbol and the second one an Array)?! Interesting point. But somehow
I doubt that there are so many cases in which you'd have to get around the
indirection. Is there any way to check this?!

Linear algebra is your friend - Trigonometry is your enemy.
