Maybe it's just me; I feel like it's more explicit when I see it together with `strict`, spelled out: `use strict; use warnings;` [download] 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. s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/	[reply] [d/l] [select]

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) :-) Open source softwares?
