1.023 Thu Nov 20 19:12:58 CET 2014
        - work around backwards compatibility breakage in perl 5.22
          (removal of PL_sv_objcount).
1.022 Sat Jul  2 02:38:21 CEST 2011
        - document how () after the function name overrides the
          prototype.
        - improve documentation, fix the examples.
1.021 Sun Jul 19 07:43:17 CEST 2009
        - try to provide compatibility to pre-5.8.8.
1.02 Sat Apr 11 06:42:06 CEST 2009
        - set NODEBUG on scope_guard, to work around -d:-modules
          causing scope_guard to be called in the wrong context.
1.01 Wed Jan 14 00:30:18 CET 2009
        - guard_free didn't return a value.
1.0  Fri Dec 26 14:03:28 CET 2008
        - un-support windows process emulation (it didn't
          work anyways).
        - discuss similar modules.
        - tweaked documentation slightly.
0.5  Sat Dec 13 22:46:46 CET 2008
        - vastly improve documentation,
          clarify local/scope_guard ordering
          and give niftier examples.
        - always bless guard objects and convert
          Guard::cancel to a method, at an 8% runtime
          cost.
        - temporarily disable $SIG{__DIE__} when executing
          guard blocks.
        - fix testsuite.
