Revision history for Perl extension B::Utils.

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.
