           Summary: Concatenation gives 'non-constant expression' outside
                    CTFE

The following code:

const ulong[] A = [1UL];
const ulong[] B = A ~ [1UL];

gives:
concat.d(2): Error: non-constant expression A ~ [1LU]

But changing it to the following works:

const ulong[] A = [1UL];
const ulong[] B = getConcat(A, [1UL]);

ulong[] getConcat(ulong[] a, ulong[] b)
{
    return a ~ b;
}
