Travis posed an interesting thought: within a body of code, which methods get sent most often? He used this little code snippet to find out:

bag := Bag new. 
bundle := Store.Registry bundleNamed: 'BottomFeeder'. 
bundle leafItems	do:		
	[:pkg | 		
	pkg compiledMethods do:				
		[:each | each resourceType ifNil: [each messagesDo: [:selector | bag add: selector]]]]. 
sorted := bag contents associations sorted: [:a :b | a value > b value].

He then did it again using a multiplier for message length. Curious, I tried that out on the BottomFeeder bundle, and discovered that I mostly send core system messages:

I see that I do a fair amount of comparisons in there - applying the multiplier::

I guess I create a lot of new objects, and work with a lot of streams :)
