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.

"IMHO, best practice for warnings is to enable them only lexically." The issue was that the lexical warnings pragma was unavailable in Perl 5.004 (see Re^2: PERL csv files to Excel). I agree that `$^W` is a poor, second choice but it is available in Perl 5.004 (see Re^4: PERL csv files to Excel). — Ken	[reply] [d/l]
