[plt-scheme] javascript s-exp transform

You have the power.

If you use the prototype-web-server
(web-server/prototype-web-server/servlets/add.ss as an example), it
will do the continuation serialization process on your whole program,
including the parts of your program that construct javascript. [Btw,
Dave Herman's javascript.plt is better than mine.] So,

(let/cc k
 (js ,(write/string (serialize k))))

will be Javascript syntax for a string representing your continuation,
serialized.
