The post is at [1] and is on reddit at [2]. With regards to Sets missing from the language: ----- struct Set(T) { void[0][T] set; // void[0] should not allocate (according to ancient manuscripts) alias set this; void put ( ) ( auto ref T input ) { this.set[input] = []; } } void main ( ) { Set!int set; set.put(1); set.put(5); assert(1 in set); assert(5 in set); assert(4 !in set); } ----- I'm not sure about any special syntax which is expected for languages which have built-in sets. It would probably be overkill to add syntax support, but I'm not sure how often people use set literals or not. |

To not force the people to invent the set interface in every project again and again. And newcomers will look for it in the standard docs, and not in ancient manuscripts. I mean it isn't obvious that one should use void[0][T]... > I'm not sure about any special syntax which is expected for languages which have built-in sets. It would probably be overkill to add syntax support, but I'm not sure how often people use set literals or not. E.g. Python has build in literals for sets. C++ has sets in standard library. I see the points against adding something like this to the core of language, but it should be at least in the standard library. |

That was 5 years ago! Why do things move so slowly...
