Yes, it looks like the do: protocol was missed, although associationsDo: 
and keysDo: were reimplemented for MethodDictionary.  Those are the 
obvious enumeration protocol for MethodDictionary -- it is less obvious 
that do: is useful, which is probably why it was missed.

The implementation should look something like:

do: aBlock 

	tally = 0 ifTrue: [^ self].
	1 to: self basicSize do:
		[:i | (self basicAt: i) == nil ifFalse:
			[aBlock value: (array at: i)]]
