Very useful and appreciated plugin which does exactly what it advertises.
I use this great module mainly for handling session based data in mod_perl applications and can highly recommend it!
Simple yet powerful.
I use it for configuration files, as a serializer, for test definitions and as a drop in replacement for Data::Dumper.
Has a few problems while dumping some data structures through (but it is able to dump data structures containing Apache::Request objects (where Data::Dumper fails)).
Anyway, YAML is one of the modules I install first on any new system :)
Great module, very useful if you've complex test cases.
Great module, at last with named bind parameters.
