Instance method

Please note that this is an instance method, not a class method (which seemed more logical for me and took me a while to see what’s wrong). So, you call it like this:

  User.new.from_json '{"id": 1, "name": "DHH"}' # RIGHT!

not like this:

  User.from_json '{"id": 1, "name": "DHH"}' # WRONG!
