Blocker Description
Reported by Marco Clemencic:
The reproducer script /afs/cern.ch/work/m/marcocle/LHCBPS-1856/reproducer.sh should print
>>> from LoKiArrayFunctors.decorators import ANUM
|
>>> from LoKiPhys.decorators import ALL
|
>>> print ANUM(ALL) < 1
|
(ANUM(ALL)<1)
|
>>> print ANUM(ALL) <= 1
|
(ANUM(ALL)<=1)
|
but it prints:
>>> from LoKiArrayFunctors.decorators import ANUM
|
>>> from LoKiPhys.decorators import ALL
|
>>> print ANUM(ALL) < 1
|
(ANUM(ALL)<1)
|
>>> print ANUM(ALL) <= 1

The function that should be invoked is in /afs/cern.ch/work/m/marcocle/LHCBPS-1856/lhcb-lcg-test/30/LHCb/InstallArea/x86_64-centos7-gcc9-dbg/include/LoKi/FuncOps.h:81 (https://gitlab.cern.ch/lhcb/LHCb/-/blob/master/Phys/LoKiCore/LoKi/FuncOps.h#L81).
What is weird (for us at least) is that the __lt__ function a few lines above works nicely.
The only hint I have is the "could not resolve" message, which suggests that the overload is correctly picked up, but the function cannot be found.
We are tracking the progress in https://its.cern.ch/jira/browse/LHCBPS-1856.
