Yep, no worries.

Agreed - apologies, I'm suffering email backlog.

Cool.

There's generators which could be cool to support, then there's support 
for the 'yield' statement. Up to now you can kinda spoof that via 
closures...

myGeneratorFunction(Closure yield) {
     for (i in 1..10) {
	yield i
     }
}

So its not really a language feature right now, its literally we just 
invoke the closure to simulate a yield. Though we might wanna do real 
yields like python/ruby/C#. But this is kinda like a mini-continuation 
inside a single method.
