Wouldn't it be helpful to have user-defined tasking for such cases? Because there is another important case for this - co-routines. When implementing stuff like network communication (e.g. HTTP servers) and parallel processing we frequently have a set of state machines (one per connection) too expensive to handle from OS tasks. Programming a state machine is turning all design upside down. If there were user-defined task support one could program this as if it were in proper tasks. -- Regards, Dmitry A.
