I would like to do something like this

## YAML-File
- !ruby/variable:x = !ruby/object:Some_Cool_Class
  para1: val1
  para2: val2
- !ruby/variable:y = !ruby/method:x.get_somethings_for_me
- new data for us
  stuff: !ruby/hash-value: y['some_key']
  other stuff: !ruby/hash-value: y['some__other_key']

## parsing Ruby-file
require 'yaml'
class Some_Cool_Class
        def initialize p1, p2
                @para1 = p1
                @para2 = p2
        end

        def get_somethings_for_me
                puts "making something really complicated"
                return {
                        'some_key' => 'some value', 
                        'some__other_key' => 'some other value'
                        }
        end
end

result = YAML.load(str)
