I'm just learning rust, and know nothing about language development, so the complexities involved might make this impractical. At the same time, it would also be really interesting to see how something like this could be incorporated to work with tuples and multiple return values....
loop over the odds array to compute the sum, and return finaly return the value. So, multiple array allocations just to compute a simple sum… Fortunately, Rust does not do that: instead, the compiler writes as great code as the first solution provided here, by itself! Let’s demonstrate...
