MarsSeed [1] filed a deletion request for pyopencl-headers-git [2]: Broken, abandoned VCS package from 2015. Uses both python2 and 3 in the same monopackage.
Not needed: extra repo carries latest stable. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/pyopencl-headers-git/
