    ! Remove support for Perl 5.6.x
      The module uses a fancy way of opening a lexical filehandle which
      doesn't work on Perl 5.6.x. Instead of trying to figure out how to make
      5.6.x open() work with an undef lexial variable for a filehandle via
      Travis CI, I simply declare this module incompatible with 5.6.x.
