I just want to note that the whole thread is almost unreadable on the digitalmars.com/webnews/, because it doesn't digest unicode chars at all. So adding unicode to D will give problems to show code. Unrelated to the unicode, but related on those opSubset, opSuperset, etc: while implementing a set() class with the same API of the Python sets, I have seen there are the following operators/methods too: issubset(other) set <= other Test whether every element in the set is in other. set < other Test whether the set is a true subset of other, that is, set <= other and set != other. issuperset(other) set >= other Test whether every element in other is in the set. set > other Test whether the set is a true superset of other, that is, set >= other and set != other. A full opCmp can't be defined on sets, so I think in D1 we can't overload <= >= among sets... I think this is a problem has to be solved in D2, because sets are important enough. Bye, bearophile
