I was playing with D for a several weeks and came up with a
swizzling implementation for a vector class. The feature is
common for languages like GLSL or HLSL. One of the use cases is
a vector cross product with only two GPU instructions.
Here is the idea:

Here is the full source of the vector:

The code allows you to write something like "const foo =
bar.yyzx" where bar is a vector and ".yyzx" constructs a new
one from it.
This is not a production code. I believe one could make it much
better. But the idea seems to be interesting in the area of
inner DSLs for D.
I'm sorry this is nothing new.
