best AJAX tool/module ?

[Rajeev Prasad]

Hello,
 
what would be the best AJAX module to use with perl?
 
is cgi::ajax best? I am not using CGI in my project so far so checking if there 
is anything else out there...
 
are there any other modules which would be easy (natural fit) to work with data 
returned in JASON?
 
please give your expert advice based on your insight into this.
 
 
thank you.
