Ruby and Continuations

I've been quietly observing the debate in the Ruby community over continuations being discontinued in 2.0. My stance is that the wrong debate is happening. It's not whether or not to include a feature. I think the debate should be "said feature should be possible". I want the power of being able to write continuations into Ruby if I want them. Why burden the language with extra features that only a few want? Make it possible for them to implement the feature themselves. If the features become popular, then include them in like you would a library. It's for this reason that I love Smalltalk and Lisp. There's no reason Ruby couldn't have the same power.
