Hi!

Did you address this:

I believe Gregg is correct, @subject works the same as @iri when given
in an object of a property, so @iri could be considered redundant
(albeit more understandable at least for @coerce). The question would
be if @iri is sugar for objects with *only* that key (an no other
properties), or if it works just like @subject.
