I like the syntax of Pascal: If X is a pointer, then "X" denotes that
pointer, "X^" denotes the object it points at (all of it!), and "X^.Y"
denotes the Y component of the object X points at (again, all of that
component!).  And "X.Y" is illegal.

Since dereference is just one character, it's not painful to read.
And it imparts useful information.
