Hi internals! Hi Nikita,

Before going any further I'd like to get some comments about what you think of adding generator support to PHP. I have always hoped to see the “yield” keywork introduced in PHP. I even suggested that in this mailing-list at least one time but I'm very glad to see some patches coming out.

In addition to Gustavo's remarks, I wonder how the GC would collect a Generator object that is not use anymore (especially with a referenced yield). Does it fit to the current CG strategy or do we need an extra strategy? I would notice that the “Yield by reference” section does not exist but you have targeted it). Moreover, I wonder how a “recursive yield” would act (something like “public function *f ( … ) { … yield $this->f(…); … }”). It is possible? Is it anticipated? Thanks for you work.
