Nice art.
I see that Scala compared to Ruby (which i currently use) is more type save for the price of writing some additional code, but still in an elegant way.

In Ruby duck typing is comparable. Ruby does not have the obligation and the ability to declare which methods must the method argument have.

Something like this:

def inTheForest(duck: Object) = { /* I mean Object as a wildcard */
duck.quack
duck.feathers
}

will work?

In Ruby it would look like this:

def inTheForest(duck)
duck.quack
duck.feathers
end
