*struct* MyNiftyPointerTo(T)

...

MyNiftyPointerTo!(C) getValue()

Read that carefully about 5 times

getValue returns a struct.  getValue returns an rvalue.  Please recognize this
before commenting again.

> It's not going away because MyNiftyPointerTo!(C).getValue is an lvalue.

MyNiftyPointerTo!(C) does not have a function called getValue, it is the return
type from getValue

Incidentally, I can type quite fast and I have never EVER wanted to save
keystrokes when it sacrifices clarity.  My protests have nothing to do with
saving keystrokes, they have to do with generic code -- writing code that works
whether something is a builtin or a custom wrapper type.
