# 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*).
