Is there a fast language that supports portable continuations?

Question

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).

Answer 1

Did you checked OCaml ? It can be compiled and should be marginally slower than C.

Continuations and delimited control

Answer 2

Scala 2.8.0将允许延续，并且它们将是可移植的。

Answer 3

While I agree that dialects of Caml might be an excellent choice I feel I have to mention Gambit Scheme. Together with Termite, an erlang-like framework it has support for serializing continuations, sending them over the wire, and much more.

It compiles to C-code.

Answer 4

Its possible to do serializable continuations in Java using Apache JavaFlow - if you do go that route then the Swing Continuations library at:

makes it the coding a lot more pleasant.
