Hi, Charles -

There is, of course ContextPart>>trace:, but are you aware of ContextPart>>tallyMethods:?
If not, try...
	ContextPart tallyMethods: [3.14159 printString].

It does almost exactly what you describe (even a bit more).

Also have you ever tried MessageTally>>tallySends:.  If not, it will blow your mind.
Try...
	MessageTally tallySends: [3.14159 printString]
