Nobody understands templates?

Yes DB, we can soldier on happily, but it would not do any harm 
to understand templates.

The documentation examples quickly make your eyes glaze over, 
looking at the code in Phobos is doubtless instructive, but you 
can wade through a lot of that without finding what you want. 
Also I discovered an interesting fact today. the word 'mixin' 
does not appear in the language reference Templates section of 
dlang.org.

It should be used in at least one example. I just discovered by 
trial and error that I could use 'mixin' in Templates (as opposed 
to Template Mixins), and when you know that it seems likely that 
you can accomplish lots of stuff you couldn't before.

While I'm here, has anyone discovered a way to fudge a 
constructor super(..) call in a mixin template that's included in 
a class constructor. Since the mixin template is evaluated in the 
scope of the constructor, it seems like it should be OK.

I'm sure I'll get there in time ;=)
