IIRC the two places where $^X breaks are:
  * VMS
  * something obscure about symlinks

FWIW, I use $^X.  I mostly use it in tests.  eg ...
  http://search.cpan.org/src/DCANTRELL/Data-Compare-1.21/t/taint.t

and have the test skip on VMS.  IIRC the other places I've used it are
for code that doesn't (yet) work on VMS anyway.
