Unintuitive: it's not clear what The "result" part refers to.  It's
such a generic word when applied to a (meta)function that it lacks
obvious semantic content... it's almost like naming the max fucntion
"result_of_max."

That doesn't explain anything (to me).  What I was asking was: why
provide this oddly-named metafunction when people could just make the
inquiry using range_iterator with a const argument?
