From STL to Ranges: Using Ranges Effectively
summary
Coverage of C++20 ranges with concrete code, three implementations tested (range-v3, cmcstl2, nanorange), and production experience on GCC/Linux; demonstrates that views are lazy and cheap to copy, shows piping vs constructor forms, explains that many algorithms return iterators and projections add a third parameter for key extraction, introduces span and string_view as contiguous ranges, notes some algorithms (accumulate/numeric) are missing and performance differences are anecdotal.
