70# 1. Put all intra-package imports at the *bottom* of the file, unless
71# they're absolutely needed before that (for top-level statements
72# or class attributes). Imports of "trivial" packages that don't
73# import other packages (e.g., 'smartdict') can be at the top.
74# 2. Never use 'from foo import *' on an intra-package import since
75# you can get the wrong result if foo is only partially imported
76# at the point you do that (i.e., because foo is in the middle of
77# importing *you*).
