The -w switch seems to be unnecessary, and the -l switch seems only to assure that a newline is spit out at the end of the print.
just commenting on that:
when i'm coding on commandline i always use -wle now. it's just automatically. without that i would have been bitten so often from a missed warning. and -l is just so convenient.
also if i copy and paste commandline code from others i find it annoying if it doesn't contain -wl
