-// The tricky part is that the pointer's mutability (var vs const) refers
-// to the ability to change what the pointer POINTS TO, not the ability
-// to change the VALUE at that location!

-//     var unlocked: u8 = 10;
-//
-//     const p1: *const u8 = &locked;
-//     var   p2: *const u8 = &locked;
-//
-// Both p1 and p2 point to constant values which cannot change. However,
-// p2 can be changed to point to something else and p1 cannot!

-//     const p3: *u8 = &unlocked;
-//     var   p4: *u8 = &unlocked;
-//     const p5: *const u8 = &unlocked;
-//     var   p6: *const u8 = &unlocked;
-//      
-// Here p3 and p4 can both be used to change the value they point to but
-// p3 cannot point at anything else.
-// What's interesting is that p5 and p6 act like p1 and p2, but point to
-// the value at "unlocked". This is what we mean when we say that we can
-// make a constant reference to any value!
