-# Module 'dump'
-#
-# Print python code that reconstructs a variable.
-# This only works in certain cases.
-#
-# It works fine for:
-# - ints and floats (except NaNs and other weird things)
-# - strings
-# - compounds and lists, provided it works for all their elements
-# - imported modules, provided their name is the module name
-#
-# It works for top-level dictionaries but not for dictionaries
-# contained in other objects (could be made to work with some hassle
-# though).
-#
-# It does not work for functions (all sorts), classes, class objects,
-# windows, files etc.
-#
-# Finally, objects referenced by more than one name or contained in more
-# than one other object lose their sharing property (this is bad for
-# strings used as exception identifiers, for instance).
