[Koha-devel] replace Data::Dumper with faster JSON::XS in Koha?

i noticed there are a few places in Koha where Data::Dumper is loaded, even if $debug is off, etc (like the Items and Circ modules) i wonder if we could replace Data::Dumper with something faster, perhaps...? like JSON::XS, YAML::XS or YAML::Tiny here's some benchmarks and discussions, etc http://martin-evans.me.uk/node/42 http://stackoverflow.com/questions/1876735/should-i-use-yaml-or-json-to-stor... any thoughts, people?
