 Allowing the trailing comma may also make programmatic code generation easier.

+Why don't generators support the with statement?
+------------------------------------------------
+
+Any time you use generators to create context managers you have to add a @contextmanager decorator.
+If you leave that decorator off, Python will then raise either a TypeError or an AttributeError 
+(denoting that __exit__() is missing from your generator). If you are using a generator in
+a context manager (the with statement) then leaving off that decorator no longer raises an error and
+now just silently fails to execute the generator body. Meaning an easy problem to detect is now a
+lot harder to find and fix. Automatically closing your generator can just as easily be done with contextlib.closing()
