| >Ah yes, explain me more the concept I've been using for a dozen years, surely I don't understand it. Apparently you don't, as you appeared confused. Whether it was just the syntax of Swift that confused you, or something more general, the parent was not a medium to know. In any case, the parent gave a general answer. If you already know some parts of the answer, you can skip them (others might not, and can find it useful) -- no need to be rude about it. >I would never have guessed the arguments thing. So? Tons of things a programming language does are not guessable if you don't know its semantics, and even less so if you also don't know its syntax. That doesn't even make them bad or difficult, just not already familiar. >I would never have guessed it's open range. I would. .. and ... are very common ways to describe ranges, and < is a logical thing to use to say it's open given its math meaning. >I would never have guessed, and I was writing in Perl with its magic variables for more than a half of my professional career and most of my studies. Well, I would have guessed all 3 of them. $0, $1 and the like are quite common, and at that place they couldn't be anything else but positional arguments. >And that's the whole point: the syntax is so atrocious that it takes training to understand it. Or it's so good that it takes training to understand it, as opposed to catering to the lowest common denominator of what people can immediately "guess". |
