To start out with catching up on patch review, I took a look over and
applied the patches on bug 23817, fixing wfObjectToArray() and FormatJson
for a case that broke certain parts of ForeignAPIRepo when PHP's native JSON
module wasn't present:

The patches were posted by Tim Yates shortly after his bug report in June
2010; the same bug was re-filed in December as bug 26250, and only
reconnected later. Thanks for the fix, Tim!
