MarsSeed [1] filed a deletion request for python-funcsigs [2]: Please delete this. Funcsigs is a backport of a Python 3.3+ standard feature (PEP362) to Python 2.6, 2.7, and 3.2. As none of the Python3 packages on AUR require Python 3.2, this is redundant. Also this addons has not been extensively tested above Python 3.5.
