MarsSeed [1] filed a deletion request for python-pylsl [2]: One-time effort from 2019, orphan, niche Py2+Py3 pkg. Broken. Seems best to delete. Was only used by the similarly long-broken and abandoned python-muselsl. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-pylsl/
