Hi Craig,

Since noone has commented on this yet, I'll take a stab:

What kind of method-lookup change? What is needed here and what are the
implications for both speed and potential impact on JIT?

I'm slightly hesitent to reserve an object format for something like method
dictionary marking. Can you elaborate on why this would be needed? I would
somewhat expect that a well-known class could do the same and we only have
so many object format types. Version bits in method trailers shouldn't be
needed if I understand the CM changes correctly - you might just add another
iVar to CMs.

Hm... something a little more specific would be nice ;-)
