Explore the evolution of C++ Standard Library from iterators to ranges in this ACCU Conference talk. Dive into the complexities of defining the Range concept, balancing theoretical considerations with practical applications. Learn about the challenges in designing range semantics and their impact on code readability and conciseness. Discover implementations of range adaptors, including transform and filter, and understand how to create more efficient versions using iterator safety and indices. Examine flexible algorithm returns, external and internal iteration techniques, and the use of coroutines in range-based programming. Investigate interruptable generator ranges, concatenation implementations, and advanced formatting techniques for containers. Gain insights from Arno Schoedl, an experienced software architect and CTO, on the future direction of C++ library design and its implications for developers.
