Indeed, and that was very helpful.

I'll remember that.

I had expected b'spam'[1] would be b'p', and it took me some to figure 
out it was 112 and that that was why my code wasn't working anymore when 
I converted it from Python 2 to Python 3. But that doesn't necessarily 
mean b'p' would have been better than 112. A case can be made for both. 
I'm aware of it now, and it's not a big deal anymore. And indeed, too 
late to change.
