-// Check this out:
-//
-// var foo: u8 = 5; // foo is 5
-// var bar: *u8 = &foo; // bar is a pointer
-//
-// What is a pointer? It's a reference to a value. In this example
-// bar is a reference to the memory space that current contains the
-// value 5.
-//
-// A cheatsheet given the above declarations:
-//
-// u8 the type of a u8 value
-// foo the value 5
-// *u8 the type of a pointer to a u8 value
-// &foo a reference to foo
-// bar a pointer to the value at foo
-// bar.* the value 5 (the dereferenced value "at" bar)
-//
-// We'll see why pointers are useful in a moment. For now, see if you
-// can make this example work!
