That'll teach me to post before testing; my code doesn't work. I 
still think it would be good to find a way to address this problem, 
but I am less convinced I have the right way, even after I fix the 
bugs. Ultimately, one doesn't want a family of template functions, 
but of classes (so that they can be used in the standard associative 
containers). Also, it would be good to be able to specify the 
comparison criterion for each sub-comonent.
