“…the barrel.” Apples don’t come in bunches, but at the time the saying was coined they were carted around like that. (Also it only took one, not a few.)

(I suppose the modern version is “one nazi spoils the bar.”)

C++ is one if those languages where writing a library feels hugely different from using it. Boost is a case in point here: there are brilliant peiple behind it, but (error messages aside) the ergonomics of using thise libs in an application are usually pretty good.

(Scala felt similar to me. There are other languages where it feels much less like I’m swapping hats as I flip between parts of a codebase.)
