This works fine, thanks a lot. I would have expected `.array`
to return a dynamic array. But apparently the compiler is smart
enough to know the length. Even the multi-dimensional case
works fine:
double[n][n] bar = 0.repeat(n).array.repeat(n).array;
I hope this is not performance-critical code. The assembly is
terrible for such code, at least for LDC, doing a GC allocation,
unrolled reset to zero, then memcpying the dynamic array back to
the stack: https://godbolt.org/g/uXBN75
`double[n] bar = void; bar[] = 0;` (2 lines, granted) results in
a memset.
