All in all nice intro, unfortunately it requires users to understand templates quite well, but honestly not sure if it is avoidable, with a gazillion customization points in ASIO. Anyone aware of a wrapper library around ASIO that doesn't offer all those customization points and maybe not the full functionality/ efficiency but is easier to use?

Maybe a sentence or two describing the rationale and complexity would be nice. I know it is O(1), but it is weird that begin/end are called on pointer. std::size_t read_lineI am tired, but is this function O(n^2)? cb += bytes_transferred; // adjust the pointer and sizeI would maybe switch to write instead of write_some to keep the code shorter, and mention write_some as another option in text. [](error_code ec, std::size_t bytes_transferred) For learning purposes I would capture something in lambda by value and note that reference capture would be buggy. using type = std::allocator<void>; Personal preference: not a fan of typedefs for relatively short types used once.
