As of (roughly) v5.6.2, -w is different though.  See perlrun and then 
perllexwarn.  With '-w', you're enabling warnings globally -- on all of 
the modules being loaded.  This is sometimes nice to check, but (e.g. 
in tests) not if the modules weren't tested with warnings enabled.

We who cut mere stones must always be envisioning cathedrals.
