Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Bar implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary) in /in/B57Kk on line 10 string(50) "O:3:"Foo":1:{s:9:"Foodata";a:1:{i:0;s:3:"Foo";}}" string(35) "C:3:"Bar":20:{a:1:{i:0;s:3:"Bar";}}"
