> the colon overload of C++

There's a lot of colons here too:

  - (id)outputImageProviderFromBufferWithPixelFormat:(NSString *)format 
                                          pixelsWide:(NSUInteger)width 
                                          pixelsHigh:(NSUInteger)height 
                                         baseAddress:(const void *)baseAddress 
                                         bytesPerRow:(NSUInteger)rowBytes 
                                     releaseCallback:(QCPlugInBufferReleaseCallback)callback 
                                      releaseContext:(void *)context 
                                          colorSpace:(CGColorSpaceRef)colorSpace 
                                    shouldColorMatch:(BOOL)colorMatch;

In other languages, a function with that many parameters would be close to unusable. Far too easy to get them mixed up. The way Obj-C forces you to name each argument is great.

Yeah, I'm not complaining, I really do like argument labels. Objective-C sometimes does go overboard with sentence-like labels, but usually it's not an issue.

Yes, but they don't come in pairs and are neatly spaced away from each other.

This was mainly meant as a joke :)
