To be honest, I think the patch is worth to be merged including other patches I submitted. Yet I believed it was better to close the pull request because I put quite some time into researching and programming the solutions but nobody really cared so I stopped. All I received from my work was a "Awaiting merge" screen on my laptop. It was really discouraging to see how things work here in the python development community so I decided to leave instead of waiting a month or more and at the end looking at the "Awaiting to merge" screen or being rejected again. Thanks Christian for asking why I closed the PR at last. Just look at the date when the patch was submitted until it was put into awaiting patch mode again then you see what I mean. If anybody still wants me to submit patches please say so instead of completely ignoring me and my work.
