On: How do we kick our synchronous addiction?

Not all asynchronous code has to use callbacks. See http://dieselweb.org/

Yeah, same with Swirl for Tornado:

However, if your async call actually happens somewhere in a library function, you have to yield also calling that function - it's not transparent for the caller whether the library function is synchronous or not.
