Hello 🙂

In the Movie graph, there is in `ACTED_IN` relationships the property `roles` which is a list of string.  
In the [documentation](https://neo4j.com/docs/cypher-manual/current/syntax/values/#composite-types), it's written that composite types cannot be stored as properties, by experience and in your `Movie` graph example, we see we can store a homogeneous list of property types. I think you should add this information to the documentation.

Regards,  
Cobra

This is actually called out under the property type section above the composite section.

> Homogeneous lists of simple types can also be stored as properties, although lists in general (see [Composite types](https://neo4j.com/docs/cypher-manual/current/syntax/values/#composite-types)) cannot be stored.

Put another way, it's always been; You can't store an array of objects, only an array of value types.  
I doubt this will ever change, since if you're storing an array of objects, that could be better modeled as relationships.

I checked before and didn't see they added it 😅
