True that warnings, strict, etc. may not be entirely necessary for programs that are only a half-dozen lines long, but:
  1. It's good to display them in sample code which new initiates may emulate
  2. You never know when your basic 6-line program may start evolving into something more substantial
  3. For some of us, -wT and use strict are such habits that it's more work to exclude them than to include them
