unique_count() - is it missing?

Hi

Am I being obtuse here or is unique_count() missing ?

I would expect that given a pair of input iterators, beginning and end, it
would count and return the number of unique instances of a containers
value
(or apply a predicate). It would take for granted that the sequence is
sorted.

It is like the difference in SQL between

SELECT  COUNT(field) FROM SomeTable
SELECT  COUNT(DISTINCT field) FROM SomeTable

Thanks
