Multi-Dimensional Analog Literals

// Have you ever felt that integer literals like "4" don't convey the true size of the value they denote? If so, use an analog integer literal instead:

// Two-dimensional analog literals are of type analog_literals::rectangle<X, Y> which exposes static member constants width, height, and area.

// Three-dimensional analog literals are of type analog_literals::cuboid<X, Y, Z> which exposes static member constants width, height, depth, and volume. In addition, three free-standing functions top, side, and front are provided which yield rectangles:

// The current implementation has one restriction on cuboid dimensions: the height of a cuboid literal must be at least its depth + 2.

// This of course defeats the purpose of using the analog literal. C++0x's proposed `auto' feature would come in quite handy here. We can actually fix this problem partially (using the stack-ref-to-temporary's-base trick used by Alexandrescu's ScopeGuard), but we would no longer be able to use the values in ICE's, and frankly I think this madness has gone far enough already.
