Good question. They're similar, but 'use warnings':
- only works under Perl 5.6+
- works _lexically_, rather than globally
- this means that you can do this:
pack
t; <[EMAIL PROTECTED]>
To: <[EMAIL PROTECTED]>
Subject: use warnings; and #!/usr/bin/perl -w

Is
use warnings;
the same as
#!/usr/bin/perl -w

For addition
No.
use warnings is file scoped. -w is 'executable' scoped. In other words any modules
that you 'use' will inherit the -w but not the 'use'.
At least that is my understanding from the Camel. And appears to be the case from what
I have seen in action.
