[BUG][TEST] ObjectsAsMethods don't understand perform:

Hi folks,

I am playing around with ObjectsAsMethods from Andreas to do some fast 
with them, but when I wrap Monticello for example, I get a 
primitiveFailed error in perform:.

Andreas acknowledged the bug already. He believes that some checking 
for the right number
of parameters is only appropriate if the method at hand is a standard 
compiled method.
He just does not have time for that right now.

I believe he means

Interpreter >> primitivePerform and friends

the according line should be

	self success: ((self argumentCountOf: newMethod) = argumentCount).
But I neither know how to ask in a fast manner if a method is a 
compiled one, nor do I have
time to build several VMs. I tried the VM-Simulator yesterday and ran 
in the same problem as Stef.

Maybe somebody wants to try Neds VM-Simulator fixes from today and help 
to build one of the worlds
fastest method wrappers?

Here is the test:

p.s. some totally unrelated fun script to produce some natural spirals, 
including the golden ratio (137.5),
should be "etoyed"...
