Under "Future directions" (http://www.codeplex.com/IronScheme/Wiki/View.aspx?title=Roadmap&referringTitle=Home http://www.codeplex.com/IronScheme/Wiki/View.aspx?title=Road...): > Complete support for inward continuations (if this is ever possible on the CLR). So it seems the jury is still out on the issue. The CLR does not support continuations natively. It could be implemented be writing an interpreter on top of it, but that would be slow. Perhaps they could be implemented by eschewing the CLR built-in stack and call, and instead compile everything into jumps or tail calls and keep a separate stack? I'm not sure if this is possible though.
