Hi,
I proposed in early february an enhancement to avoid having redefine hash and = together and I would like to see it integrated in 1.3.
My idea is that the implicit link between these two methods should be supported by the system.
A first solution is proposed on the issue tracker
http://code.google.com/p/pharo/issues/detail?id=3657To make instances of some class comparable, simply make the class use the TEquality trait.
TEquality relies on message valuesToCompareForEquality sent to objects for both = and hash.
The default implmentation of this message is provided by Object.
Override ONLY valuesToCompareForEquality method for custom equality check.
