- babyrainbow 9y ago>The syntactic-sugar form isn't there with the @.. But those things are differences, right? Certain languages makes certain things easy and idiomatic. The differences in languages are all about that...
- alexandercrohde 9y agoSo there are two options: 1. Join the languages (so PHP would get that syntatic sugar too) [or preferably never have so many in the first place] 2. Be where we are now, where we have redundant libraries, frameworks, languages, package-managers, version idiosyncrasies, and IDEs for mere syntactic sugar.
- babyrainbow 9y agoEh? Two options for what? I was talking about how languages are different...
