What binary arithmetic operators do you need that real[]

OMG silly me! I can already do a[] /= b[]... D is great! :-D
Thanks a lot!
Also:
a[] = b[] + c[] * d[] - 42;
and so on... All that's required is that there is pre-allocated
memory for the result to go in i.e. there has to be enough space
in a[].
You should be aware that with DMD these array operations should
be much faster than a straightforward loop, as they are done in
handwritten asm using vector instructions. Be wary of using them
on very small arrays, there is some overhead.
With LDC/GDC you probably wont see much difference either way, if
I remember correctly they rely on the optimiser instead.
