Integrating Packages into squeak.

Integrating Packages into squeak.

Commenting on "Overrides in newest Monticellos?"

Why do overides keep cropping up?

In looking a packages, people lose sight
 that each of the packages have to be joined into squeak.

The joining, how is that done?

I don't have a good complete answer to that.

Everytime I have tried it has entailed
 adding to classes more core than my additions.

Some methods are at the very crossroads
 of all the behaviors that a new package wishes to modify.

PasteUpMorph>>mouseDown:  is an example. 
Loook at its history.
Its been modified and remodified to accomodate
 new behaviors in other packages.

Menus and menu building methods are another crossroad. 
Eventually I have to write something that overides
 the version of an earlier package.
And if my addition is to be removable then what happens?

It is about time something like that is included as a basic part of
Smalltalk.
