A Journey into Ranges, Views, Pipelines, and Currying
summary
Walks through turning a command‑line file listing (an Advent of Code day 7 example) into C++20/23 ranges pipelines using spanstream and istream_view, shows filter_view/take_view composition into a lazy pipeline (saved as a variable named DaveBrubeck) and demonstrates debugging with custom emit and eval utilities that force evaluation to inspect element‑by‑element flow. Shows currying via stacked lambdas to supply extra predicate arguments, compiles on GCC 12.3 but not on the uploader's clang setup; utilities are for debugging, not production.
