----------------------------+-----------------------------------
 It seems that the operator== on NumericTypes has some issues when used
 with other Typelib Types

 require 'orocos/log'

 Orocos.initialize
 Orocos.load_typekit 'base'

 val = Orocos.registry.get('/base/samples/frame/Frame')
 puts val === val.superclass # prints false
 puts val == val.superclass  # prints false

 val2 = Orocos.registry.get('/double')
 puts val2 === val2.superclass  # prints false
 puts val2 <=> val2.superclass  # prints -1
 puts val2 == val2              # prints true
 puts val2.superclass == val2.superclass  # prints true
 puts val2 == val2.superclass  # raises `==': wrong argument type nil
 (expected Data) (TypeError)
 puts val2 != val2.superclass  # raises `==': wrong argument type nil
 (expected Data) (TypeError)
