Occasionally, a programer who knows what they're doing will create code which causes a non-fatal error to be printed that they know is OK. In such a case, use warnings will allow you to put a no warnings for the area of code in question, but keep the warnings for the rest of the program. OTOH, using -w would require you to shut off warnings for the entire code.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
