A library for effect handlers in C++

Nice! By coincidence I'm ging to present my bachelor's thesis today - partially in effects and handlers.

Isn't this kind of thing supported natively with C++ coroutines as of C++20?

Just because it is C++ does not mean there is any merit in doing an &quot;object-oriented&quot; thing. Use of inheritance just makes it clunky.<p>I.e., this is a clever idea, but the form could be better.
