Ok, now I'm not sure I follow. Apart from the performance issues, why can't you replace every method that "yields" with a method that takes the explicit block parameter, and .call() it?

sigh yeah... you could do that, but you often times you have to deal with methods that aren't invoked that way.

No it is not. You dodged the question again, by throwing a hardly related blog of someone else at it.

How many people will use yield _AND_ self.send in the same method please?! That seems like an awfully complicated and contrived example. Who the heck does this?
