What makes you think it does not return a class object? It does.
But note that you have to use a symbol (#Object) not a String
('Object') when you use #at:. Of course. '#Object' does not make any
sense. If you use #classNamed:, both a String and a Symbol will work.

This doesn't work either, because again (Smalltalk at: aClassName)
is returning just a ByteString but not (e.g.) Object class
or (e.g.) ClassBuilder class .
Lets assume in the calling method is written:
returnSuperClass: '#Object'.
Note: the Argument must be an instance of String.
returnSuperClass: aClassName
|aSuperClass|
aSuperClass := (Smalltalk at: aClassName) superclass.
^ aSuperClass.
Nope, this does'nt work.
