> c# and ruby fibres (altho i think ruby removed them, ultimately?

Ruby did not remove Fibers (in fact, they’ve been recently, in 3 0, enhanced to optionally be nonblocking—that is, automatically yielding on any operation that wpuld block.)

Ruby removed continuations from the core (moved them to stdlib) after adopting independent Fibers way back with 1.9; continuations were the previous mechanism for similar lightweight concurrency.
