I propose to change the yield convention in Trollius to "yield From(x)". This is similar to "raise Return(x)". The reason is that this way it will be easier to convert Trollius code to Tulip code automatically. Without this, you have to look at each yield in the code and decide whether it's in a coroutine or in a regular generator, and only convert them when occurring in a coroutine.
