Hm.  That's a reasonable and practical stylistic convention, but one
I've been on the fence about in my own thoughts.  At first blush it
seems it would be a hard line to draw sometimes.

In any case, (on a quick search) I don't see this in the Python or Zope
style guides.  Is it worth mentioning one of those places, or does it
fall somewhere closer to "common sense" than "style"?

Partly historic, partly because I didn't think about it, but now that
I *do* think about it, I think it's right they are methods: they can do
some non-trivial computation (calculating the size of a persistent
BTree requires faulting in the buckets).
