[Python-modules-team] Bug#844368: pyparsing: version 2.1.10 makes sphinxcontrib-doxylink FTBFS

Hello all,

This or a related regression also affects systemd's hwdb parser [1].
With 2.1.8 it is still working fine:

$ LC_ALL=C.UTF-8 hwdb/parse_hwdb.py
WARNING: evdev is not available
hwdb/60-evdev.hwdb: 31 match groups, 44 matches, 114 properties
hwdb/60-keyboard.hwdb: 124 match groups, 192 matches, 643 properties
hwdb/70-mouse.hwdb: 63 match groups, 92 matches, 72 properties
hwdb/70-pointingstick.hwdb: 6 match groups, 16 matches, 8 properties
hwdb/70-touchpad.hwdb: 3 match groups, 5 matches, 3 properties

(in a clean unbuilt checkout), but with 2.1.10 it completely fails to
parse anything:

That sure does look like some API change which shouldn't happen in a
microrelease?

Thanks,
