I am working on a project that will be using your fiber library in a manner similar to how sym_fiber is intended. Before you released this update I was planning a design using the asym_fiber (which looks like the old 'fiber') that would simply call 'run()' on the fiber it intended to 'switch to' under the assumption that I could have any other fiber 'resume' by calling run on it again. The only apparent difference is that with 'yield()' you go back to the caller and with run() you go to some other context (which could also be the caller).
Perhaps I am missing something fundamental, but I didn't see a need for two different fiber's.
b.run(); // == a.switch_to(b);
a.run(); // == b.switch_to(a);
