Well, there are more systems than POSIX compliant ones around. I wonder
if dropping this kind of compatibility with old UNIX systems is done
for a good reason.

Do we really need to write
  awk '{ l = $0 }; END {print l}'
instead of "tail -1" now (to be portable to all todays UNIX systems)?

Is this the progress that POSIX brings to us?
