GP here. Yeah I don't think I’m blubby in that sense. I used to work daily in Rust, including with custom collection types. And lots of other language experience with iterators. Go has maps and slices, and slices fit 99% of my use cases. You can index, reslice, concat, append, sort, sort by, clone, and yes, iterate with range (although the range syntax itself is merely a small convenience). As for the chaining, yes I do miss filter and map but is again totally doable with vanilla slices (they just haven’t added those methods to the slices package).
