Okay, but what interface do I bind it to? *, so it's available on all 
objects? It just seems a bit wasteful, a view is essentially a 
multiadapter for a context and a request. A macro needs neither context 
nor request, and feels a lot close to a utility to me.

I want to get it from one define place, but only be accessible either 
from trusted code, or by people who are allowed to view it.

Well, my way wasn't much typing, but I hit a problem.

<browser:page name="mymacro" template="my_macro.pt" ... /> seems to have 
a TAL version of 1.5.

Products.Five.browser.pagetemplatefile.ViewPageTemplateFile seems to 
instantiate templates with a TAL version of 1.6.

So, if I try and use my macro from a normal Five view, I get a 
METALError: macro 'mymacro' has incompatible version '1.6'.

Why is that? How can I fix it and get them both to use the same TAL version?

cheers,

Chris
