As Far As I Know, A Grammar Has Nothing To Do With Comments. The
Scanner Usually Skips Over Comments In The Source Code Already,
Such That The Parser Doesn'T Even See Them. However, You Can Write
Your Own Scanner And Parser, That Make Comments Explicit In The Grammer.
But If You Want To Allow Comments _Anywhere_ In Yout Language, The
Good Luck!! :-) That Grammar Is Going To Be A Mess....
