//
//	Eventually(c).Should(Receive())
//
// This will timeout if nothing gets sent to `c` (you can modify the timeout interval as you normally do with `Eventually`)
//
// A similar use-case is to assert that no go-routine writes to a channel (for a period of time).  You can do this with `Consistently`:
//
//	Consistently(c).ShouldNot(Receive())

// You can pass `Receive` a matcher.  If you do so, it will match the received object against the matcher.  For example:
