+A binding can be avoided by using a single underscore in place of the expression to match on; in this context the underscore represents an _anonymous argument_.
+``` purescript
+case _ of
+  0 -> "None"
+  1 -> "One"
+  _ -> "Some"
+```
+
+This is equivalent to
+```purescript
+\x -> case x of
+  0 -> "None"
+  1 -> "One"
+  _ -> "Some"
+```
