 Yes, I can:

 <tal:block define="items here/get_some_items" repeat="item items"> 
   ... etc

"items" is actually the sequence the 'repeat' repeats over, and is
defined in the same block as the repeat. If the 'repeat' is executed
before the 'define', the sequence to be repeated over is undefined.


 Did I miss something here? I have not understand the "__future__"
import, I admit.
