Comment (by ayeshrajans):

 Awesome to hear about bumping version to 7.2! I work quite a lot on legacy
 code, and from what I have seen, PHP 7.2 can raise some PHP notices that
 are often not seen from tests or and pop up in edge cases. I have worked
 on a few tickets for 7.2 and tests are passing(yay!), but personally, I
 think there is still a room for improvement.

 One very frequent problem with 7.2 is that count() calls on uncountable
 variables raise a notice. This kind of bugs are very difficult to grep
 from the repo and often missed from tests. `count()`, `each()` and such
 deprecation notices are easy to fix but annoying nonetheless. If we can
 actively hunt those bugs quickly as they are reported, that can help a
 lot.
