title: Are Traits good or bad?
body: <p>This is an open-ended question, but I would like to solicit some opinions from the SO community on Traits; do you think Traits in Squeak/Pharo are a good thing, or should you stay away from them and use composition and delegation instead? I ask because while I know how to use them (thanks to the Pharo book), I am not really sure how acceptable it is to use them or where it is OK to use them and where it isn't.</p>
