0.06 ???
    - Ask CLKAO

0.05_09 Sat Apr 6 16:09:.. CEST 2008
    - Allow for nested disjunctions in opgrep patterns.

0.05_08 Sat Apr 5 22:58:.. CEST 2008
    - I-am-a-muppet.
    - Removed spurious use of Data::Compare.

0.05_07 Tue Apr 4 18:15:.. CEST 2008
    - opgrep() can now capture sub-ops so if you plan to
      extract information from or modify a deeply nested
      op-tree, you don't have to do the tree-walking
      yourself.

0.05_06 Tue Apr 3 18:15:.. CEST 2008
    - Add the as_opgrep_pattern() method to B::OP for
      dumping op trees as patterns for matching with opgrep.
    - Add warnings.
    - Documentation fixes.

0.05_05 Tue Apr  1 18:15:.. CEST 2008
    - Fix POD error and update README.

0.05_04 Tue Apr  1 18:10:.. CEST 2008
    - Fix bug in opgrep() alternations.
    - Add the "kids" keyword to the opgrep syntax.
    - Add the "dump" keyword to the opgrep syntax for debugging.
    - Fixed the Change log (yes, this file) for the last
      version since the comment on an opgrep() change was
      incorrect.

0.05_03 Sun Mar 30 11:13:.. CEST 2008
    - Fix various bugs in opgrep(). Did that work in 0.05_02 at all?

    - Add a longer example to opgrep() documentation.
    - Fix POD markup.
    - Add a clear license statement to the docs.
    - Use a string as version -- otherwise it might not be flagged
      as a development release!

0.05_02 Thu Dec  1 ..:..:.. ... 2005
    - ->parent works for all tests now.
    - Added more tests.

0.05_01 Fri Oct 28 23:00:00 CST 2005
    - Added tests. That's the focus of my work right now.
    - opgrep() now acceps \@conditions
      assertions may be code references
    - Lots of changes to ->parent. This is in progress. It fails when
      the parent of a node does not exist in the execution pathway of
      a program. The unused null() ops rooting some conditionals, etc.

      This function fails tests.
    - Added a function recalc_sub_cache so anon_subs, all_starts, and
      all_roots' cache of functions can be cleared.
    - Added functions ->siblings, ->ancestors, ->descendants, and
      _uniq_ops.
