It can be used to enforce some compile-time and run-time constraints on
what keys are valid in a hash being used as an object. This can be set up
using the fields pragma.
But it's generally underused. It was added then mostly forgotten about.
Whoever added it may have had some grand visions of where they intended to
go with it, but that generation of perl core hackers are all long gone.
