The problem is that TS uses the same strange array notion of PHP to have 
an array type that mixes numerical indices with named indices.

I'd try to untangle that so that ContentArray takes only numeric indices 
by definition.

As a consequence eg the old PAGE object would have to be changed to look 
like this:

x = PAGE
x.content.10 = Text

Other objects that don't need ordered arrays, could have properties that 
implement named arrays. eg the meta property of the page object:

x = PAGE
x.meta.author = Masi
