A "class" is instantiated to 0..n objects.
A "singleton class" is instantiated to 0..1 object
A "metaclass" is instantiated to 0..n Class Objects

Ruby has no metaclasses.

No one can insist on this.

The correct term would be "exclusive object" (or something similar, but 
_not_ metaclass, which has a specific meaning):

The diagramm (V1.3) demonstrates this.

So, readers can now decide who's right and who's false.
