This all seems fair enough. My concern is mostly that the `blob.method(fn)` syntax seems much easier to get your head around (as someone familiar to JavaScript) than the `[for (let x of iter) if (pred(x) transf(x)]`. I always used the traditional syntax for LINQ in C# as well (which gave you both options). Perhaps I'm just too set in my ways though. I'm happy to accept that it's probably easy enough to just rely on `Array.from` when you want an array from an iterator.

In addition to what others have already said, note that iterators model streams that are not necessarily finite. Hence, a toArray method would not generally be well-defined. /Andreas _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
