Dave Abrahams's suggestion does look workable.  I was a bit 
worried about there being an ambiguity with

  cout << format(s) << 1 << (format(s2)) << 2; 

But it appears that placing the parenthesis caused an
error which removed the ambiguity.  :-)

The format of strings by themselves would be something like

  string s= (format("%d != %d) << 1 << 2).str();

(note, no endf here as that would hide the .str() function.)

charT will definitely get done at some point.  Though resolving the
first set of problems is of the most immediate concerns.  

I think I have enough ideas to start implementing something which
matches closely which what boost wants. (though I am certainly
open to more feedback.)
