Thanks for the great talks!

I'd like to add one more thing: IMHO the greatest value of PStore and
YAML::Store comes from their ability to restore object graphs of real
ruby classes, both standard and custom ones, so you don't need to deal
with manually re-instantiating your objects when restoring:

require 'yaml/store'
store = YAML::Store.new('store.yaml')
store.transaction { store['times'] = [Time.now] }
restored = store.transaction { store['times'] }

p restored #=> [2014-08-08 15:07:28 +0200]
p restored.first.class #=> Time


YAML::Store provides human readability and better compatibility, but can
be slower than PStore.
