+// There's a shorthand to initialize Arrays with a certain size that does not 
+// require you to type in 100 items (but you certainly can if you want!)
+// Check out the Primitive Types -> Arrays section of the book:
+// http://doc.rust-lang.org/stable/book/primitive-types.html#arrays
+// Bonus: what are some other things you could have that would return true
+// for `a.len() >= 100`?
