I’m looking for a fast language (ie. a language that can be compiled natively to achieve performance not more than 3 or 4 times slower than C), which supports portable continuations. By this I mean a continuation that can be serialized on one computer, and deserialized on another.
I know that SISC can do this (a Scheme implementation in Java), but its slow. Ditto for Rhino (a Javascript implementation in Java).
Scala 2.8.0 will allow continuations, and they’ll be portable.
