     Well, once I have built a string, I want to use it.

     I find the .replace() line rather ornamental.  I have even more
complex parameters so I came up with my .Set() method.  I am surprised
that there is no such functionality in StringBuilder.

     I understand your example.  Either I have learned, you write good
examples, or both.
