Implement parser changes to support C#-like syntax for lambda expressions.
Examples:
x -> x + 1
(x) -> x + 1
(int x) -> x + 1
(int x, int y) -> x + y
(x, y) -> x + y
(x, y) -> { System.out.printf("%d + %d = %d%n", x, y, x+y); }
() -> { System.out.println("I am a Runnable"); }

Note: 'thin' arrow is still used (instead of 'fat' (=>) arrow a la C#). This will be a topic for further refinement.
