[Haskell-beginners] Wildcards in expressions

[Tom Murphy]

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
