The latter is preferable over the former (less code, less maintenance).
But often people put utility methods like #on:, #with: etc on the class
side, for non-trivial initializations.
When you say "sent automatically by Behavior>>new" is that true? In other
words:
x := abitraryObject new.
results in an attempt to call arbitraryObject>>initialize?
From the (re-)usability point of view, if you had getters/setters (like
in traits), the perfect approach is
x := MyClass new setY: 'text';
setZ: 0;
yourself.
Or, like I prefer to do it
(x := MyClass new)
setY: 'text';
setZ: 0.
I suppose we don't worry much about the "waste" of, say, setting up some
features with default values and then having to discard those when the
user sets them to something actually useful?
