- there IS a difference between $a = 3; and $a = "3"; even though undetectable by regexp - this patch has been used in production for months - as of now the original couchdb-client by maverick still has this wrong - encode_json is the fastest stable serialization method in Perl - example: now it's possible to query view with params ?key=[3,"3"]

I replaced LWP::UserAgent with WWW::Curl::Easy. Retrieving 1000 documents from DB now takes 3.3 seconds whereas with LWP it took 6.3 seconds (4GB RAM, 4 cores, 32bit Fedora).
I also changed the behavior of dbExists method which is now much faster when there is 20+ dbs in Couch because it does not load the complete database list.
