Hi Xavier,

I also like that feature.

... which is why I wouldn't fiddle with cObj->data, because it is not
intended to be used like that. It expects data['uid'] etc.

Why not introduce a new ->dataArray which could be anything implementing
the "Iterator" class? This allows much more flexible ways of passing
data to this LOOP without having to "pre-fill" an array.

And I was thinking: would this be more like a new feature on top of
"CONTENT"? So that you could say CONTENT.selectArray (selecting from the
internal array) instead of CONTENT.select (which selects from SQL)?

Maybe we then also need some ways in TypoScript to manipulate this new
dataArray? :)

Cheers,
Ernesto
