Overview
– This file contains all sorts of little compatibility hacks that we’ve had to introduce over the years. Quarantining them into one file helps us know when we can get rid of them.
Ruby 1.9.x has introduced some things that are awkward, and we need to support them, so we define some constants to use later. ++
