FWIW $ is not only used for the RHS of a slice

char[] str;
str[$/2..$];	// 2nd half of array
str[$-1];	// last element in array
str[$-5..$];	// last 5 things in array
str[$-10..10];	// um... well... you get the idea

I would think this would be the same thing.

auto foo = [1,2,3];
auto bar = [4,5,6];
auto result = foo ~ bar;

am I missing somethign?
