It was the operator detection that I was particularly thinking of.  However, 
I'd like to mainly restrict additions to type_traits to those traits that do 
actually work without user specialization if possible.  IMO that would be 
more in keeping with the rest of the library... on the other hand we do have 
is_union... so I guess some non-functional traits could be added if they 
"complete the picture" as it were (and particularly if some kind soul would 
write them up for possible TR2 additions :-)

HTH, John.
