I see what you mean but would disagree :) . Working with the php context only brings only a structural advantage. IMHO practically it's comparable with a pure php implementation. Where it might be ok for generators as the lexer must be touched anyway, I was talking about the base for spl_coroutine mentioned by Laurence. Also, some sane implementation do exist. Not only oss (see the links in my previous mail), but even in the premium products, just to be said. Of course it's complex, but doable, may be not right at the first step.
