I saw another pattern based on respondsTo:
SARInstaller>>initialize
"SARInstaller initialize"
(FileList respondsTo: #registerFileReader:)
ifTrue: [ FileList registerFileReader: self ]
It is used in SMLoader
TTFont and may be some other places.
Why do you do that. Why FileList registerFileReader: self is not enough.
registerFileReader: and unregisterFileReader: methods are key methods
for the registration
so not having them does not make a lot of sense.
So what were your assumptions?
