Cuis is an exploratory environment -- the system reflects upon itself.

Opening an Installed Packages Browser

Command-click the Morph, select menu: debug->`browse morph class`

Note CodePackageListWindow>>deletePackage in the `commands` method 
category.

Note `CodePackage deregister: current` in the code.  Select and ask for 
`implementers`.

Note `self installedPackages removeKey: aCodePackage packageName.` which 
suggests that the action of delete/merge is to remove knowledge of the 
named Package and so consider its code just a part of the current image.

As a quick check, you can `Feature require: 'FFI'.` (or any small 
package).

Open the Installed Packages browser and delete/merge the FFI package.

Open a Code Browser and note that the package code still there.  [Test 
assumptions]

Close the image without saving. -- just a test..

Become an explorer!  Cuis welcomes this!

Good on ya,
