Please note that env assumes that everything before EOL is one
argument, hence if you say

  #!/usr/bin/env perl -w

it looks for a program "perl -w".  In order to turn warnings on, use

  $^W=1;

in your script or, if desired,

  BEGIN {
    $^W=1;
  }

The latter turns warnings on before the script is compiled, otherwise
warnings are issued only at run-time.
