C and D are instances of metaC in that.
class metaC( type ):
def what( self ):
return self
class C( metaclass= metaC ): pass
class D( metaclass= metaC ): pass
assert C is C.what() and D is D.what()
#print( C.what(), D.what() )
C= metaC('C',(),{})
D= metaC('D',(),{})
assert C is C.what() and D is D.what()
#print( C.what(), D.what() )
furthermore.
