This PR was merged into the 4.3-dev branch. Discussion ---------- [PHPUnitBridge] Static access in closure | Q | A | ------------- | --- | Branch? | master for features | Bug fix? | no | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | n / a | License | MIT | Doc PR | n / a #29718 bumps php to 5.5 . This is what we could simplify if it gets merged, thanks to this "new" PHP feature: https://3v4l.org/sJOWr EDIT: it was merged, this can be reviewed.
