If CF7, just setting a using type/returntype is slow (vs. not doing so).

still like that info there so

That just makes it object-based. However, it has inheritance,
polymorphism (because it has dynamic dispatch via inheritance)

Because of the overhead of performing overload resolution - which

I think the answer lies in between yes and no. It has properties that lend
to OO. It also has properties that are very structural in nature. Can it
be used in a manner similar to OO...by means yes. Is it pure OO...no.
