As far as I can see, forcing the programmer to write identifiers in an only-ASCII language, and requiring that identifier names have to be meaningful to the programmer means that the programmer has to know a language that is written in only ASCII. Most people are not, and requiring that they first learn for example English to be able to write programs is absurd. Of course, if we relax the rule that identifier names have to be meaningful to the programmer, then it works out, but that is not something that I feel the Swift community should encourage. The few symbols that are in English can be learned as what they are, symbols, without knowing their English meaning, just like &, |, <, >, *, and so on are symbols. In fact, you all learn these words as symbols that are distinct from their English connotations, since Swift is definitely not English text. /Magnus _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
