According to this article:

…Ruby 2 will not have continuations. Is this true? If so, why  
would continuations be dropped? It’ll be pretty tough to implement  
RHDL without continuations.

so will Ruby lose continuations right about the time Python is getting  
them?

I think this has been clarified in a few other forums, but it seems that  
the situation is as follows:

- YARV does not support continuations now
- YARV can support continuations, but it’s not a high priority
- Ruby 1.9.1 + YARV probably won’t have continuations
- Matz does want continuations to eventually be supported by YARV

I believe the “no continuations in Ruby 2.0” stemmed from a translation  
of Matz or ko1 comment at the Ruby Kaigi…or at least, that’s where I  
got it from. I guess the general recommendation is that if you need  
continuations and would like to see them available in the 1.9 series  
sooner, you’ll need to cough up a compelling use case.

If continuations become something everyone really must have, I’ll try to  
find a way to make them work in JRuby. For now, they’re unsupported.
