[Newbies] MorphMorph new / Morph newStandAlone Difference ?

[John-Reed Maffeo]

David,
Your answer was very helpful. It enabled me understand Smalltalk better.

#newStandAlone is implemented in #Morph with the expectation that the
method #initializeToStandAlone will be overridden in subClasses. The
comment in the method is long and I did not understand it. I still don't
quite understand why the same behavior cannot be implemented in #initialize.

By reviewing the implementors of #newStandAlone, I see that the behavior is
required(?) to create an object that can be used in a PartsBin(Flap?), but
not all classes assign the method to the category #partsbin; it also
appears in the categories #initialization and #miscellaneous (which should
ideally be changed for consistency, which I would be happy to do if
appropriate).
