Further to kcott's reply:   Note also that -w controls the global $^W special variable and enables warnings everywhere in your code.

This means that -w used in a program that use-s or require-s a module that actually generates warnings may suddenly start spewing them out like Mr. Creosote and ruin everyone's evening. IMHO, best practice for warnings is to enable them only lexically.

Give a man a fish:  <%-{-{-{-<
