impl Mul<Array<Complex<T>>> for T #1260
Description
I did a quick scan of the issues and didn't see this. For an array: Array<Complex<f64>> (for example), i think it's perfectly reasonable to expect
let output: Array<Complex<f64>> = 2.0_f64 * array;to work. I've only ever gotten a rhs mul e.g. array * 2.0 to work. (see example, non-working example). Is there a reason this hasn't been done, e.g. orphan rules?

I think it should be possible, actually, here's an example

The implementation can also be done for

Also, doing this for

Just for baseline/background. I don't know if this is a good idea, don't know if there are any drawbacks. Since complex implements mixed float-complex operations, we have the necessary precedent to consider it.

I believe this would be closed by #782? The next-gen compiler will enable that PR and seems to be close to stabilization, as it is a Rust goal for 2024.
