I would really like to have a way to specify that a class is abstract.
For example I would like to be able to write a test as follow
self assert: (Collection allSubclasses reject: [:each
each isAbstract ]) new isEmpty
now saying that isAbstract is if a class has one method sending
subclassResponsibility is not
really good for me.
May be we could have something like
isAbstract
^ self declaredAsAbstract
or: [ (self whichSelectorsReferToSymbol: #subclassResponsibility)
isEmpty not]
