I found this one of the significant advances of Quixote 2.  "$" prevents
the need to split strings or put the referent away from its placeholer.
This makes it easier to visualize the output from the template, because
everything is in order and there aren't any extra line breaks or quoting
in the middle.

It would be nice if Python 2.4 were universal at this point and we
wouldn't need this, but it will take a year before everybody can
upgrade.  My application for instance has to run on a Mac, and
Macintoshes are still at Python 2.3.0, and Apple installed it in such a
way that upgrading it is just asking for trouble.

It would be nice if Quixote's substitution recognized global variables
too.  Otherwise you have to assign them to local variables with
different names or use the default-argument kludge.  But that's a less
significant issue.
