Supported methods are not available as field names

Let's say that we have next object: contentNodes = {}

Supported methods are not available as fields name

? "contentNodes.items = " contentNodes.items ? "contentNodes.count = " contentNodes.count

On Roku:

    contentnodes.items = invalid
    contentnodes.count = invalid

On BRS:

   contentnodes.items = [Function items]
   contentnodes.count = [Function count]

So, on Roku expression: if contentnodes.items = invalid or contentnodes.items[0] = invalid then is valid but while running tests not.
