Class definitions in the Objective-C 2 runtime have a "base protocols" list which lists a number of protocol definitions, each of those defintions have another protocol list, which in turn defines another set of protocols.

I'm wondering if there is any restriction on how deep this "recursive" list behavior can go.

Also if the way this works is if class Foo conforms to protocol FooDelegate, and FooDelegate definition conforms to BazProtocol and BarProtocol, if they are defined as follows:

Class Foo:
...
protocol list -> (count: 1) [ FooDelegate ]
...


FooDelegate:
...
protocol list -> (count: 2) [ BazProtocol, BarProtocol ]
...

BazProtocol:
...
protocol list -> (count: 1) [ NSObject ]
...

BarProtocol:
...
protocol list -> (count: 0)
...
