Lets use the bitshift composition across all tutorials and examples. Regarding context managers, I still have a divided opinion. It makes sense to use them. But sometimes I tend to not use them just to make my code cleaner as I get an extra tab space to put my code in. So let's leave that to users but maybe add a comment like you said earlier to show thw users that we can use `with` statement ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
