----------------------------------------
0.004008  Sat Sep 12 13:16:30 2015

    - Promoted $VERSION variable to earlier in source to
      attempt to placate cpanminus (thanks, Karen!)

    - Added prototype to overridden caller()

    - Changed way caller() is overridden, hopefully will no longer
      clash with Sub::Uplevel
