[#65851320] Fix failing test in about_object.rb (the number 1 is an object)
[#65851320] Fix failing test in about_object.rb (the number 1.5 is an object)
[#65851320] Fix failing test in about_object.rb (the string 'string' is an object)
[#65851320] Fix failing test in about_object.rb (nil is an object)
[#65851320] Fix failing test in about_object.rb (object is an object)
[#65851320] Fix failing test in about_object.rb (123 to a string is '123')
[#65851320] Fix failing test in about_object.rb (nil to a string is '')
[#65851320] Fix failing test in about_objects.rb (inspecting 123 yields the string '123')
[#65851320] Fix failing test in about_objects.rb (inspecting nil yields the string 'nil')
[#65851320] Fix failing test in about_objects.rb (the class of an object's id is Fixnum)
[#65851320] Fix failing test in about_objects.rb (two given objects do not have the same id)
[#65851320] Fix failing test in about_objects.rb (false always has an object id of zero)
[#65851320] Fix failing test in about_objects.rb (true always has an object id of twenty)
[#65851320] Fix failing test in about_objects.rb (nil always has an object id of eight)
[#65851320] Fix failing test in about_objects.rb (zero has an object id of 1)
[#65851320] Fix failing test in about_objects.rb (1 has an object id of 3)
[#65851320] Fix failing test in about_objects.rb (2 has an object id of 5)
[#65851320] Fix failing test in about_objects.rb (100 has an object id of 201)
[#65851320] Fix failing test in about_objects.rb (clone indeed creates a different object)
[#65851320] Fix failing test in about_objects.rb (further proof, their object id differs)
