Answer 1

If you need nested objects to be converted as well.

# @fn       to_hash obj {{{
# @brief    Convert object to hash
#
# @return   [Hash] Hash representing converted object
#
def to_hash obj
  Hash[obj.instance_variables.map { |key|
    variable = obj.instance_variable_get key
    [key.to_s[1..-1].to_sym,
      if variable.respond_to? <:some_method> then
        hashify variable
      else
        variable
      end
    ]
  }]
end # }}}
