MazeChaZer [1] filed a orphan request for psysh [2]:

I contacted the maintainer several weeks ago via email and wrote a comment here in the AUR a few weeks ago. The current maintainer isn't responding and the package has been out of date for a year or so now. I volunteer to update and maintain the package.
