It's faster, because there's no method lookup, no message send, no 
suspension point. The commit message is misleading, because all, but the 
last comparison in this loop is done between a Symbol and an Array. So in 
almost all cases it saves 3 message sends, while in the last case it saves 
one.
Actually I don't expect that it saves that much of total runtime, but why 
not use this property of Symbols and have better performance for free?
