What's the difference between use warnings and use warnings FATAL => 'all'? What's the rationale for using the latter instead of the former? And where are the differences between the two uses documented?

I'm asking these questions because, within the last year or so, I've seen a lot of instances on PerlMonks and Stack Overflow where someone uses use warnings FATAL => 'all' in place of the more often-recommended, canonical and simpler use warnings.
