Re: What is -w?

Hello htmanning,

The -w command line switch is like use warnings; except that whereas the latter is lexically scoped, -w is global. That is, -w activates warnings in used or requiredd modules as well as in the current file. So I find it hard to imagine how including it could actually remove an error.

Can you post the code? Or better yet, can you create a minimal script which exhibits the same behaviour?

Hope that helps,
