Unless, of course, you really wanted to know whether
Character class
knows about #cr. But bear in mind, Character class is not
the “class side” of Character but the Metaclass of Character
Character class isKindOf: Metaclass "=> true"
The “class side” of Character is simply Character
Character isKindOf: Class "=> true"
The “instance side” of Character is, you know it,
a character itself
$a isKindOf: Character "=> true"
==
So, if you want to know whether the “class side” of
Character knows of the method #cr, the correct one is:
Character respondsTo: #cr
