Can you please add a pollAny?

[joe9]

Hello,

Thanks for sharing the library.

Just want to check if you could add a pollAny function? or, if you have any objection to having such a function?

Thanks

Bear in mind that it will have cost O(n). If you're ok with that, and there's a valid use case, I suppose I don't have any objections.
