ADL discovered free function synthesising an exception type from an error type, used by the .failure() observers.

Extracts a boost::system::error_code or std::error_code from the input via ADL discovery of a suitable make_error_code(T) function.

Extracts a boost::exception_ptr or std::exception_ptr from the input via ADL discovery of a suitable make_exception_ptr(T) function.
