I assume you mean:

  var tester = test();
  tester();

And yeah I agree, straight functions seem way nicer, which is what the coroutine() wrapper in the writeup ends up accomplishing.

Javascript 1.7 copied the generator/coroutine objects straight from Python, and it's a weird fit...

One thing that you can't do with just a function is have the .close() method, which may or may not be a fundamental issue.

I mean you could refer to the function by its name, and then run it with () when ready.

Oh, so you really did mean `var tester = test;`

The reason that might be less good than the current approaches is that you may want to spawn multiple 'instances' of the generator/coroutine. If I'm understanding your proposal correctly, you'd only ever be able to run it once.

Oh, that's a good point. Didn't consider that.
