The examples you gave are exactly the ones I mean with generic solutions. Stuff you can apply to many things, like lambdas. Such things exist in many programming languages. Yes, that's stuff people should learn and keep up with. But using some weird quirk or very uncommon language construct just to save a couple of lines of code (and show how well you know the language) - tempting, but just don't. And use long, understandable variable names! Don't be a mathematician, you're an engineer! (totally unrelated but its just really annoying)
