Recursions are quick, pushing registers to stack takes nanoseconds if at 
all. That's nothing from php point of view. Did you actually measure a 
performance gain or is your patch an assumption?

Why? Your first 'if' only fails if there is no such class (-> error out 
-> exception -> no production code). Thus, the second class_exists() in 
while() is always called, so no reduction of class_exists() calls. Where 
is the difference to the recursive method? Did I get something wrong?
