If you change the behavior of a standard system utility, then you
must be prepared to fix every program written before and after that
uses the standard.  You could, of course, extend "awk" to provide
the service you want (by adding an option, or changing the
syntax), just make sure it's compatible with the rest of the
world.  And be prepared for the screams of those who believe that
no tool can ever be improved.

Alternatively, you can make any changes you want without worrying
about compatibility and call the result son_of_awk.
