Granted.  :)  I was really just trying to be illustrative, not neccessarily thorough. 
(Take a look at the /glaring/ error in my other exmaple... which, in hindsight, probably 
should've been more complete|correct than this one.  Oh well, that's what I get for 
posting while half asleep.)

But you make a good point of the sort that belongs in a FAQ somewhere, actually.  I've 
seen plenty of opCmp's defined along these lines in other code.
