[Pharo-project] Are the any Fuel file analysis tools/techniques?

[Yanni Chiu]

This scenario has happened a few times... Stuff is serialized and 
de-serialized (to/from files) without problem. Code changes are made. At 
some later date, I notice that the Fuel file is orders of magnitude 
bigger than it used to be.

I usually manually de-serialize, and navigate the structures until I 
find the cause of the bloating.

Is there some package or code snippets that can quickly summarize the 
object classes and sizes in a serialized file, or from its in-memory 
de-serialized form?
