Interessante Diskussion über Methodenname auf der Cocoa-Dev-Mailing-List (Link):
One of the Objective-C runtime’s unit tests includes methods with names like
@selector(idret::::::::::::::::::::::::::::)
That’s 28 unnamed parameters. (The test fills every parameter register with a value, to make sure objc_msgSend() doesn’t trample them. Some architectures have a lot of parameter registers.)
