It shows. ClassBuilder isn't actually that hard to understand. The  
constraints are hairy, but the code is fairly straightforward and has  
lots of comments.

In SystemEditor, those constraints are encapsulated in ClassFormat,  
with unit tests. The tests probably aren't as complete as they could  
be, but it gives us a place to document issues as they come up.

I'm looking forward to reenabling atomic commits in Monticello2. The  
speed improvement there is even greater, because right now, MC2 takes  
a speed hit from loading instance variables one at a time.
