In general, you can convert a string / symbol to the method it is maning by
using the method "method"
http://ruby-doc.org/core/classes/Object.html#M000336


def one()     "hi"      end
def two()     "hello"   end
def three()   "hola"    end

method_names = private_methods(false).reject { |name| name.size > 5 }
method_names # => ["three", "two", "one"]

method_list = method_names.map { |name| method name }
method_list # => [#<Method: Object#three>, #<Method: Object#two>, #<Method:
Object#one>]

method_results = method_list.map { |meth| meth.call }
method_results # => ["hola", "hello", "hi"]
