That would break the compatibility with PHP < 7 since nullable types were introduced in that version, it's not a big deal but i prefer to keep it until possibile. Maybe removing the type declaration just for this methods is enough, i will investigate it.

I've chosen to proceed in the way i described opening a new pull request #70, i'll close this one, thank you anyway!
