Nevermind, I found it -- great minds, I guess.  Wow, quit monitoring the
group for a few months and look what happens...

Anyway, my objectives are a bit different than back_door in that:

1.)  There is NO WAY I want users to have full access to ruby.  I wanted
something as benign as <r:if_parent> but more flexible.  I wouldn't build a
site for a business and then hand the secretary or office staff that kind of
a weapon.  I'm not even sure I'd trust myself if the site was important --
after all, there's no way to test whether your code breaks your live site
without breaking your live site (no real testing environment).

2.)  I want something that designers and other non-coders could use.  I
don't want them to have to learn ruby.  My thoughts here are probably closer
to John's (can I say that?) when it comes to throwing in the kitchen sink --
just enough and no more... done elegantly (by the way that phrase is now
trademarked, John)

3.) I wanted to give the extension developer a way to easily expose values
from their creations and use them in conditionals -- yet also control what
can be freely accessed and what is protected.  Again, flexibility with
security.

4.)  I wanted something that was on a separate layer from the underlying
ruby code.  That way if Radiant 4.2.5 changes the way page titles are
accessed, I only need to update my extension code -- not all my static pages
that now have Radiant-specific back_door code.

5.)  On a different note, the 'vars' stuff I created is different (though
I'm sure that you could build that using back_door and Ruby code).

Please don't misunderstand me -- I LIKE having back_door available but the
needs driving this are very different (hey, that's why we have extensions).

So, yes, it does conflict with the <r:if> and <r:unless> tags that Aitor
created (I frankly love that he also used cond="" -- ha!)  I suspect that
most developers would opt for one OR the other, though, based on their
security needs.
