Well, I was earnestly sharing run-of-the-mill Koa code since you made async abstractions sound elusive. Didn't realize you just had an agenda.

The thing is that people are actually using Koa/co to solve this problem. I've yet to see someone use fibers as their core webapp control flow abstraction.

What agenda do I have ? I have none, I'm just saying using generators do not abstract async calls. The only way to do that is by using fibers. I'm not pushing for anything, i'm just saying that something like rails couldn't be written in nodejs , (and no sails , is nothing like rails in terms of complexity ).

It's your fiber agenda. My mother used it to try to make me eat my brussels sprouts and I thwarted that, too.
