v2.18

        * TEST: More testing in scope_leak.t.

        * TEST: More testing around packages in truncate.t.

        * SPEED / INTERNAL: Significant improvements in load time,
          especially when autodie is used across multiple files,
          by caching reuseable subroutines and reducing calls to eval "".
          Huge thanks to Niels Thykier, who is a hero of the
          free people, and completely and utterly awesome.
