I know, there even was a discussion about this recently on emacs-devel. This is an interesting issue, that arise way more relevantly about domain names, usernames, web searches, or spam, etc. than for source code, as if you use free software from trusted sources, this is just as likely to happen than willingly-too-complex obfuscated programs, or bad-names obfuscated programs, etc. This two aren’t a reason from banning other languages from texts such as domain names, nicks, etc., nor for, for instance, putting restrictions in a language about the complexity of anything such as function length. And moreover that’s not a reason for banning other languages from identifiers, as C11, all lisps, and one SmallTalk showed. Unicode, or intermixing several languages, is in itself a modern issue, as more and more languages begin mixing writing systems, it becomes mandatory, yet indeed it is badly done, and centralized, and such, but it is standard and existing. > And don't forget about emojis. They indeed pushed it pretty far, but hey, that’s their fault… And if you implement unicode, you get functions to know what category of character a character is, so you may as well exhaustively ban emojis, or only allow letters, or letters and digits, or and so on. I don’t know what’s the norm for SmallTalk, but C11 for instance, afair, allow *at least* any letter or digit from any alphabet. So that should include arabic as well as maya digits, as well as arabic, chinese, hangul, cyrillic, etc. _______________________________________________ help-smalltalk mailing list help-smalltalk@gnu.org https://lists.gnu.org/mailman/listinfo/help-smalltalk
