Class protocol:

accessing
o  builtin

initialization
o  initialize
do we really need this?


Instance protocol:

lookup
o  lookupMethodForSelector: selector directedTo: initialSearchClass
Following C code is just a performance optimization.
It is not necessary, however it speeds up UI code,
since it heavily uses perform:

o  lookupMethodForSelector: selector directedTo: initialSearchClass for: aReceiver withArguments: argArrayOrNil from: sendingContext
This method is no longer sent by the VM as it nows pass
inline/poly cache object.


** This is an obsolete interface - do not use it (it may vanish in future versions) **

o  lookupMethodForSelector: selector directedTo: initialSearchClass for: aReceiver withArguments: argArrayOrNil from: sendingContext ilc: ilcCache
Invoked by the VM to ask me for a method to call.
The arguments are: the selector, receiver and arguments,
the class to start the search in (for here-, super and directed sends)
the sending context and the inline/poly cache (instance of
PolymorphicInlineCache).

The returned method object will NOT be put into the inline- and
polyCache bu default. To update the call site's cache, you have to
call ilcCache bindTo: method forClass: initialSearch class. If you
don't call it, inline/poly cache won't be updated and next call
won't be cached (therefore it will be relatively slow.

If I return nil, a doesNotUnderstand: will be send.
