<pre>From the document, "The Objective-C Programming Language" which can be found in
xcode organizer -> documentation -> search for it, it says:
"Protocols can’t be used to type class objects. Only instances can be
statically typed to a protocol, just as only instances can be statically typed
to a class. (However, at runtime, both classes and instances respond to a
conformsToProtocol: message.)"
Neither xcode nor clang offer any hints to this fact when attempting to write
something like:
- (void)doSomethingWithClass:(Class<MyProtocol>)class</pre>
