This will come in very handy over at the PHP-FIG, as we can specify
return types for interface methods instead of just type hinting parameters.
All for it. This has been done in a way that is fully BC, resolves any
of the previous complaints, offers useful functionality, does not bite
off more than it can chew, ignores the whole "nullable AND specific
type" black hole and gets the job done.
Best of luck with this one Levi.
