Missing (and future?) C++ Range Concepts
summary
Range concepts and library changes that enable real optimizations and compile-time metaprogramming: adds approximate-sized ranges/reserve_hint to propagate size hints through views so join/transform can reserve efficiently; introduces a push model with a for_each_while customization point (and optional continuous-chunk callbacks) so join/transform/read-file become direct nested loops and enable memcpy-style appends; supports compile-time-sized heterogeneous generators (tuple-based) to build concat/filter/compile-time SQL strings; prototypes live in think-cell’s range library, most ideas work but some require C++26 or standard discussion.
