# Since we have so many mutual imports in this package, we should:

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