I use several (:include:) to build up the sidebar for instance. It goes
something like this:

In Site.SideBar
	
	...
	(:include SideBar-groupspecific:)
	...

which allows me to optionally create a page 'SideBar-groupspecific' in a 
group and have it automatically appear in the sidebar when you're visiting 
a page in that group.

I use this technique in many places, i.e. using (:include:) to "pull-in" 
something only if the corresponding page exists. Hmm... thinking about it, 
I wonder if I'd like to have something like this:

	(:include PagesToInclude* :)

In other words, allow a wildcard in the include directive and include a 
bunch of pages in one go. Or perhaps somehow using (:pagelist:) with a 
special template to not just list the pages, but also include them. Or 
perhaps just an excerpt of each page.

Anyway, in the case of the sidebar, if 'invisible failure' wasn't
possible, I'd have to use something like

	(:if exists SideBar-fieldspecific:)
	(:include SideBar-fieldspecific:)
	(:ifend:)

For me it's very convenient to have include fail without an error message.
