I think if we did have an "api prefix" expression translator, it ought
to have a more declarative behavior, e.g. tal:attributes="src api:
context/url". I'm not sure "/" is the best character to use here, for
I've had a different idea for some time. In code:
def some_view(obj, request):
context = get_context(obj, request)
Then, in the template, tal:attributes="src context.url".
This emaciates the idea that a context-object isn't a model object;
it's a model object in the context of some request. I think this
follows the Zope 2 interpretation of "context" quite well.
