Are you trying to concatenate the arrays or sum their elements?

Here's how to concatenate:

	auto r = a1 ~ a2;

Here's how to sum:

	auto r = a1[] + a2[];

Everybody knows about concatenation.

With the latest 2.059 I'm getting 'Error: Array operation a1[] + a2[] not implemented'

Must be a bug with 2.059, works in 2.058.
But, why aren't there operators for arrays without having to specify "[]"?

    int[] a, b;
    int[] r = a + b;

Pointer arithmetic maybe?
