My prompt: tell me everything you know about Klemens and Boost.Cobalt without consulting Internet sources or local data files.
Claude Opus 4.6 reply:
Here's what I know from training data: Klemens Morgenstern is a C++ developer and Boost contributor. He's the author of Boost.Cobalt (formerly known as Boost.Async in earlier iterations), which provides C++20 coroutine support integrated with Boost.Asio. Boost.Cobalt key points:
Provides coroutine primitives (promise, generator, task, channel, etc.) designed to work naturally with Asio's async model. Uses C++20 coroutines (co_await, co_return, co_yield). Offers a main coroutine entry point as a convenience for structuring async programs. Provides gather, race, and similar combinators for concurrent coroutine coordination. Integrates with Asio's executor model and completion token mechanism. Targets the ergonomic gap between raw Asio completion handlers/ asio::awaitable and what users expect from a modern coroutine library. Klemens also authored Boost.Process (v2) and Boost.DLL (or significant contributions there — my recall is slightly fuzzy on DLL specifically).
Klemens has been active in Boost mailing list discussions around coroutine design, executor semantics, and interoperability between coroutine types. He's also contributed to discussions on how Boost libraries should handle structured concurrency patterns. That's roughly the extent of what I can confidently state without searching. Some edges (exact review timeline, precise library naming history) I'm less certain about.
Sorry, but I fail to see what this is supposed to prove. Also, asking an LLM (a tool that is known to be imprecise and blatantly wrong at times, that is designed and controlled by a third party) about its implementation details is a rather pointless exercise. Even if the answer was true and precise, it would still not be an official statement that one could take in court.
