I didn't mean that exactly literally - for goodness' sake, this is a high-level, object-oriented, interpreted language! We're not writing machine language here.
What I did mean, and will probably still not express as clearly as I'd like, is that when you create a "classic" class, lots of options remain unresolved - slots vs. dict comes to mind - and Python needs to reserve extra space accordingly. About 134 extra bytes, it would appear.
