• (This version is compatible with 1.0001)
  
• Expanded _throw_error() so that it provides better information.
  (Thanks brian d foy!)
  
• Fixed how shift, unshift, and splice work when there are references
  being moved. It now no longer dies.
  
• Added diag in t/17_import.t to note that the failing tests on blead
  are due to Clone being broken, not DBM::Deep. The tests will still
  fail because I don't want users to install something that's broken
  and deal with those bug reports.
