Summary0007957: add equals function to the object
DescriptionWhen starting to use Object Oriented approaches to write a common library ( like the ones present in C++ and Java) it became apparrent, that the built in object class should have an equals function.
"equals(in object Other)"

Without it becomes necessary to create a common base class (comparable) from which all other classes must be derived from, in order to use common data structures and algorithms.
If this function could be added to the object class, an unnecessary layer of abstraction would be elimintaed.

Also would make it possible (as in C++ and Java) to compare objects based on the internal meaning, rather then their object instances.

I have fixed the example so that it actually does what one would expect from a comparison between rectangles and squares, please review

I optimized it a little bit further:
1. The comparison to this is the first type of check, because it is the fastest one
2. Rectangle has always 4 sides, so there's no need to check the number of sides nor have a function returning it in this example.
3. I replaced the function for returning a length of a rectangle side with functions returning its width and height which are the properties one would usually expect from a rectangle object.

Please check.
