https://docs.moodle.org/dev/Moodle_and_PHP7#Can_I_use_PHP7_yet.3F
which suggest 'test,test,test' but like all, am seeking if anyone
has 'tested, tested, tested' (do hate re-invention of wheel).
So, the bottom line questions:
1. Has anyone upgraded PHP to PHP 7.0.x running Moodle 2.9?
2. IF so, what, if anything, broke that was core?
(I do understand addons might have issues).
Thanks, in advance, for any such experiences shared.
