I've been writing "AJAX" applications in perl since well before it had the name AJAX. i haven't really used any special tools.
There exist some modules on CPAN for JSON conversion into and out of perl, but a) JSON doesn't fully work on older browsers (like IE's older than 6), and b) we'd written a version (which produces much uglier javascript that works on older versions of IE) well before JSON became a buzzword, itself.
I don't know what to tell you, exactly... some folks might be working on some clever tools, somewhere, that present a useful abstraction on AJAX, but I know that I (and my team) just deal with the complexities of it. Granted we've built some tools (you know, some simple javascript libraries to manage the synchronous and the asynchronous http requests and such). But these are just tools to make the task easier, nothing that really abstracts away the fact that there are these requests coming and going, triggered by DHTML events and so on. I don't know if anyone else has.
