object-design code-reuse smalltalk inheritance
When talking about Smalltalk, there is definitively an over use on the possibility to add messages to Object class. It is so easy to do it, that people usually do it just to get something working fast, even if the coding is poor. There are a lot of messages (mainly #isXXX messages) that do not belong to Object and represent a bad design decision. Most of them are implemented there because they are “handy” and easily “reused”. For example #-> or #assert: implemented in Squeak. Definitively not all objects should respond to them.
