Many people have requested that operator co_await be overloaded to behave as a TRY operator when supplied with an Outcome type.

Outcome does not implement that extension, nor will we accept PRs contributing support for this. We think you should use BOOST_OUTCOME_CO_TRY() as this will lead to more maintainable and future proof code.

However, we deliberately do not get in the way of you implementing that overload yourself in your own Outcome-based code. Just be sure that you document what you are doing loudly and clearly, and be aware that future C++ standards may have a proper operator try overload mechanism.
