+Syntax:
+	- "_" as a keyword (?)

+Original: fun firsts x y -> match x,y with
+| (a,_),(b,_) -> a,b (* This (* is (* a nested *) *) comment *)
+| _ -> x.3 (* That doesn't make any sense *)
+
+Expr: Abstract(firsts x y, Match(Pair(Var(x), Var(y)), (Pair(Pair(Var(a), Var(_)), Pair(Var(b), Var(_))), Pair(Var(a), Var(b)))(Var(_), Apply(Var(x), Int(3)))))
+Result: fun firsts x y -> match (x, y) with
+| ((a, _), (b, _)) -> (a, b)
+| _ -> x . 3
