It seems to me that Morph submorph elements could be given names  
from the user interface and
this would define automatically instance variables or something like  
that with the given name.
And this has even been used to find morphs to send messages to.  
Because, besides "findA:" and "submorphThat:",
there is even: submorphNamed:

in CodeHolder, there is this wonderful piece of code:

buttonWithSelector: aSelector
	"If receiver has a control button with the given action selector  
answer it, else answer nil.  morphic only at this point"

	| aWindow aPane |
	((aWindow := self containingWindow) isSystemWindow)
		ifFalse: [^nil].
	(aPane := aWindow submorphNamed: 'buttonPane') ifNil: [^nil].
	^aPane submorphThat:
			[:m |
			(m isKindOf: PluggableButtonMorph) and: [m actionSelector ==  
aSelector]]
		ifNone: [^nil]
