I see that the rumor that Ruby 2.0 is dropping continuations is spreading. Can anybody provide a definitive reference? The best I can find is this, and the decision doesn’t seem quite as final to me.
I was joking with Tim Bray yesterday over IM that I should take on a binding of REXML to libxml2 as a Christmas project, make sure that the cornerstone of the implementation depends on continuations, and deliver it a full year before Ruby 2.0 comes out. I would of course make sure that it has better spec compliance than the current REXML regex based implementation (my personal hot button), but I suspect that the draw would be the performance benefits.
