Straying wildly off-topic, but the first form is preferable from the compiler's 
point of view.  It means that the class of the receiver is known at compile 
time, which means that we can have a better stab at speculative inlining.  

This is currently only done in an experimental optimisation pass on my machine, 
but it will probably become one of the standard Objective-C passes used by 
clang for the GNUstep runtime sometime this year.
