Faster, Safer, Better Ranges
summary
C++ ranges often lose performance and can be unsafe; this describes a concrete alternative: Flux v2 implements an internal-iteration-first model with resumable iteration contexts (single-pass iterables) plus a separate collection protocol using ordered, bounds-checked positions. The library turns standard input/forward/contiguous ranges into fast iterables, produces SIMD-friendly code comparable to hand-written loops, eliminates the earlier UB/crash case by enforcing bounds, and remains interoperable with STL algorithms and containers.
