The official docs do to. To get the "ugly" signature you have to look at the actual source, or example the method definition in the official docs. They go out of their way to make sure to present an easy-to-understand version for actual users. Which is why every actual Scala developer rolls their eyes at someone bringing up CBF. You have to go out of your way to try to be confused about it. And if that digging stops at finding the method signature, well, probably serves you right for being confused. ;-) Is CBF amazing? Probably not. Is it some sort of confusing eternal battle for most Scala developers? Absolutely not. I mean just look at the official docs, find out where he got these weird examples from, and then tell me this is a well reasoned argument.
