Research direction

Compare the working and non-working Rust Playground examples linked in the issue, then review the existing right-hand-side multiplication behavior and linked pull request #782. Done means the left-hand scalar expression produces the expected Array<Complex> result without violating Rust's orphan rules, with coverage for the reported example.

Written by the indexing model from the issue text.

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?
