It's been ages since I settled on -w instead of use warnings. I know
there's a difference, I have some vague recollection of -w being
"better", whatever that means, but it's one of those things that I
have "known" for so long that I no longer know what I once knew :-)
All my perl books -- scratch that, I just googled for it. -w is all
or nothing, and especially it enables warnings for modules which might
be better off without warnings. So it says.
But that advice seems a mite stale nowadays. It says use warnings was
introduced in 5.6, so any older modules will possibly barf, or any
newer modules which turn warnings off for their own reasons. So why
would I care about this now? I don't recollect any untoward warnings
in years of programming Perl.
