 ## Introduction
 
 While Swift's `Sequence` models brings a lot of niceties that we didn't have access to in Objective-C, like `map` and `filter`, there are other useful operations on sequences that the standard library doesn't support yet. One current missing operation is  `count(where:)`, which counts the number of elements in a `Sequence` that pass some test.

 ## Motivation
 
 Counting the number of objects that pass a test has a wide range of uses in many domains. However, Swift currently doesn't give its users a simple way to perform this operation. While the behavior can currently be approximated with a `filter` and a `count`, this approach creates an intermediate array which it immediately discards. This is a bit wasteful.
