Hmm...  This sounds like it might work for me.  I'll take a closer
look.

Sorry about that.  Is it hard to read because of:

   a) the formatting
or:
   b) lack of commenting
or:
   c) use of template metaprogramming

where the first paragraph of my reponse hopefully makes the *goal* a
little clearer.
