I see.. 
So it is the  use-macro statement that takes the datastructure, and turns it 
into a tempate/html.

I my case I think I will rather try to use a wrapper approach.
In script: return container.ajax_tpl(mcr=my_macro_from_big_tpl)
In ajax_tpl: <div metal:use-macro="options/mcr" />

But it's good to know the other option allso.

Thanks.

In other words, a script can return a macro, but is has  to be into a 
use-macro tag. 

OK 

Thanks.
