Ah - I think I see what you're doing - it's slightly different to my
macro problem (and maybe macro's have the same bug). For my problem,
I simply needed to know what resources were provided by a template
(what macros it defined).

In your case, you're defining a lookup after you're using it. It's not
immediately obvious how I can make this work - the Lookup tag needs to
know it's content. Hmmm -  I could probably move the item_dict creation
machinery from to_html to the first call of lookup_html. This will have
to wait till I have more time (or you can try it yourself).
