AudioSource.IsPlaying() would be nice

Animation has Animation.IsPlaying(string name) to check if a specific animation is playing. It would be nice to have something similar for checking if a specific audio clip is playing, e.g. AudioSource.IsPlaying(AudioClip clip).

(And I know that there are ways of keeping track of it myself. I'm just pointing out that it would be convenient if it was built in.)

And what if you want to check if a clip started with PlayOneShot() is playing?
