    default encoding, converting this name to a Unicode object before passing
    it back to the Operating System would result in a Unicode error, as Python
!   would attempt to use it's default encoding (generally ASCII) rather

    values mutated the dicts.  Making the code bulletproof slowed it down.

+ Library
+ 
+ - Cookie.py now sorts key+value pairs by key in output strings.
+ 
+ - pprint.isrecursive(object) didn't correctly identify recursive objects.
+   Now it does.
+ 
+ Tests
+ 
+ - New test_mutants.py runs dict comparisons where the key and value
+   comparison operators mutute the dicts randomly during comparison.  This
+   rapidly causes Python to crash under earlier releases (not for the faint
+   of heart:  it can also cause Win9x to freeze or reboot!).
+ 
+ - New test_pprint.py verfies that pprint.isrecursive() and
+   pprint.isreadable() return sensible results.
