Thanks for the link.

In Perl you can replace

    #!/usr/bin/perl -w

with

    #!/usr/bin/env perl
    $^W=1;

or

    #!/usr/bin/env perl
    use English;
    $WARNING=1;

It is described in Larry Wall's book.  Maybe many Perl programmers are
not aware of this because it is not always easy to guess a good
keyword to search for in the index.  I must admit that I spent some
time to find it out too.

Regards,
   Reinhard
