FastStack is dynamically resizable data structure optimized for fast iteration over the large arrays of similar elements avoiding memory fragmentation (e.g., update and rendering cycles of a game scene). Judging by the benchmarks, it faster than seq on highly fragmented data, and almost as fast as seq on non-fragmented data.
