I don't think "import" should be highlighted.  It's not a Perl builtin
function, it's just a subroutine.  Your line is equivalent to:

      'Mac::StandardFile'->import;

The only qualification I'll make is that the import() subroutine just happens
to be one that Perl knows about, like DESTROY or whatever.  I suppose DESTROY()
and friends are in blue, but import() seems to have a different flavor.  I
suppose I don't have strong feelings, though.

You can just do
   eval "use Mac::StandardFile";
if you don't want to do the require/import combo.
