Hi everyone,
     Any suggestions?

Given that

          someList :: [(a,b,String)]

, the expression

          (_, _, "Tom") `elem` someList

seems so intuitive that, even though it doesn't work, I've been searching for several hours for something similar.

     Do any of you know a way I can pull this off? I know there are plenty of ways to get the functionality, but something similarly intuitive and succinct would be great.

Thanks for the help,
Tom
