use strict;
use warnings;

But I confess that I still don't trust -w on Windows (even though I now know it works perfectly well), because Windows ignores the first part of the shebang line.  To test this, you can do:

#!/usr/path/which/does/not/exist/perl
[download]

and it'll still run Perl correctly.  Granted this isn't a reason to stop using -w, which still does work as I mentioned, but it did make me suspicious of the whole top line for quite a while.

Don't get me wrong :-) I always use warnings ever since I knew it instead of -w switch. Being a pragma gives it more power and flexibilities. I don't use Windows but I knew from the start that shebang doesn't work on it, althought Apache seems to honor the switches. However, one should take advantage of the pl2bat converter to keep his/her original switches attached to the shebang.

Still, whenever I see -w with the shebang I won't bother to change it to use warnings; or recommend to do so (unless one needs more control on warnings), it's still equally explicit, and still perfect for me (with use strict; of course) :-)
