@rrva Conceptually, it is the same. Just a different name for the same concept. https://en.wikipedia.org/wiki/Fiber_(computer_science)

This does not apply then when comparing the kotlin flavor to quasar? http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4024.pdf

It is the same. The difference some people put into Fibers vs Coroutines are immaginary and is invented by those people who think they are different. E.g., it might be one immaginary difference in C++ and a completely other difference somewhere else. In fact, it is the same concept.
