Creates an invariant accessor that allows getting and setting from the same endpoint. It will operate in getter mode if you don’t pass any arguments when calling it, otherwise it will work in setter mode. Useful when needing to chain methods (you can’t chain standard attr_writer methods because of the ‘= something` part) or when trying to create a nice looking DSL.
