Ruby's "yield" and "blocks" are not coroutines

Sorry I'm tired of repeating it, but even if Rubyistas claim it, yield / blocks are not coroutines, they are syntactic sugar for callbacks.

And I think Matz is to blame for choosing the misleading term "yield" in this context.

(Like Larry is to blame for some misleading "List" <-> "Array" terminology)

And BTW Perl5 has coroutines, passing parameters is just ugly to implement and I'm not sure about the performance gain.

Go take a look at the goto &sub syntax.
