Scala - can a lambda parameter match a tuple?

Question

So say i have some list like

val l = List((1, \"blue\"), (5, \"red\"), (2, \"green\"))

And then i want to filter one of them out, i can do some

Answer 1

This is about the closest you can get:

 val m = l.filter { case (n, s) => n != 2 }

It's basically pattern matching syntax inside an anonymous PartialFunction. There are also the tupled methods in Function object and traits, but they are just a wrapper around this pattern matching expression.
