For example: 10.iota.ahead(3).drop(2).writeln; // [2, 3, 4] 2) > it embeds a fixed-size buffer and moves through it with minimal effort. It's assumed are only shallow which can change? auto arr = 10.iota.ahead(3); auto a = arr[1..$]; // [1, 2] arr.popFront; auto b = arr[1..$]; // [2, 3] With "minimal effort" a would be [2, 3] as well. 3) Should there be ahead!3 to allow using a static array as buffer in order to avoid allocation? 4) Should there be support for providing your custom allocator for the runtime flag to allow GC-free behavior? -- |
