Notes on actually implementing the PHP 5.5 version bump:


 * ✅Create parameter-function wrapper -
 * ✅Create php55lint job -
 * Add php55 jobs for master & new release branches, but not old ones
 * Announce to wikitech-l changes, and wait for wmf.13 branch cut
 * Drop php53 jobs from master & new release branches
 * Merge version bump in mediawiki/vendor -
 * Merge version bump in mediawiki/core -
 * Update MW Codesniffer to require [arrays, like, this], and release it
 * Set up separate branch for 5.3 compat?
 * Bump MW core codesniffer dependency, and do mass conversion to square bracket arrays
 * For fun, we should see how many bytes this shrinks the codebase.
 * Start converting extensions, etc.
