This is a review? This gives me virtually no useful information -- it's the opinion of an anonymous monk, without any backup in hard facts. Nothing about what's found lacking, why it's good for quick testing of web services, or why other languages might be better (not to mention that I don't really think of "module review" as the right place to do language considerations -- a particular module probably shouldn't be used to compare whole languages).

"the restriction posed by the Perl language": what restriction would this be?
