Well.. this is where things start to get fun. (o8
I have a dirty great array.... along the lines of :
[ [ 'string', 0, { 'name':'value' } ], [ 'string', 0, { 'name':'value' } ] ]
(I love python.. the same thing in C/C++ would take HEAPS of work :)
So, I iterate over the array... that's working fine...
Then, for each iteration, I handle the data however...
I wind up with:
<dtml-in "_['sequence-item'][2]">
<!-- do stuff here -->
</dtml-in>
But that's where the problem begins.

So, you're saying that by creating a list with one element which is a
dictionary... ?
