The Thing (1982)

That would be a loss for memory.

That might be an issue with who invokes your program.

C:

Problem → return Solution;

C++:

Problem →

const [auto]&& (Problem&& problem) noexcept(noexcept( Solution<Problem>{}(std::forward<Problem>(problem)) )) { return Solution<Problem>{}(std::forward<Problem>(problem)); } -> decltype( Solution<Problem>{}(std::forward<Problem>(problem)) )
