def againstListsIIIPatternMatching(res0: Int): Unit

Same koan as above, but we are pattern matching a list with only one item!

def againstListsIIPatternMatching(res0: Int): Unit

To obtain the second element you can expand on the pattern.

def againstListsIVPatternMatching(res0: Int): Unit

To pattern match against List, you can also establish a pattern match if you know the exact number of elements in a List:

def againstListsPatternMatching(res0: Int): Unit

To pattern match against a List, the list can be broken out into parts, in this case the head x and the tail xs.
