In considering Bruce Tate's Beyond Java, Tim Bray says Bruce claims that the "Continuat Ion" facility, commonly found in Dynamic Language-s, snaps neatly onto the problem of making the Web look like a linear dialogue. Clearly, continuations are kind of hard to understand and not for casual or novice programmers. No problemo, says Bruce, frameworks like Sea Side (layered over Small Talk) hide the weirdness and let you just carry on an orderly dialogue with a user via a Web browser. In my mind I was screaming "No! No! No!" because I've generally felt that the pain and complexity involved in Object Relational and object-XML and object-Messag Ing mapping outweigh the benefits; that if your application is based on exchanging messages, then the message exchange has to be visible to the application programmer. I'm not alone in having this kind of reflex. Well, it seems that both Ruby On Rails and Sea Side would tend to disagree, and the evidence is building up on their side. Sam Ruby challenges the Scalabil Ity of this.
Do any of the Python Web Framework-s use Continuat Ion-s?
