TEST PLAN
---------
1) prove t/db_dependent/Reports_Guided.t
   -- fails
   -- note the failure has a scalar function-like bracketing
2) apply patch
3) prove t/db_dependent/Reports_Guided.t
   -- passes
4) git diff origin/master
   -- note all scalars have been changed to not have
      function-like brackets which could be incorrectly
      parsed.
5) run koha qa test tools
