v0.72

    - Our tests have been broken on perl 5.19.* (soon to become
      5.20.*) for a while because of the new warnings about given/when
      being experimental, which would fail one of the tests where we
      weren't expecting extra output when testing our command-line
      invocation.

      But the whole use of given/when and ~~ in the codebase was just
      a stupid youthful indiscretion, those features of perl suck,
      this release kills all uses of them with fire in favor of just
      using if/elsif and =~, which is all we used them for anyway.
