(eieio-class-name (make-instance 'my-class))
=>
Debugger entered--Lisp error: (wrong-type-argument eieio--class #<my-class
my-class-158f4e54cbbc> class)
signal(wrong-type-argument (eieio--class #<my-class my-class-158f4e54cbbc>
class))
eieio-class-name(#<my-class my-class-158f4e54cbbc>)
eval((eieio-class-name (make-instance 'my-class)) t)
On the other hand:
(eieio-object-class-name (make-instance 'my-class))
=> my-class
