I read in Simon Cozens’ book “Beginning Perl” that -w switch for warnings would be deprecated going forward. Is this true or is it still ok to continue using -w rather than “use warnings”.

The perlrun documentation (see
perldoc perlrunor this page) indicates that the -w option is still available as of Perl 5.12.2. Using the pragma gets you nifty benefits though, like turning warnings on lexically and finer grained warnings.Here is a blurb on why you should use the pragma instead of the command line option.
