I assume you mean that you've allocated memory on the D side,
like this:
```
auto a = new double[24];
a[] = 1.6;
Slice!(double*, 1) s = a.sliced();
```
and you want to pass s to R for further analysis.
Unfortunately, that will not work. R functions only work with
memory R has allocated. It has a single struct type, so there's
no way to pass s in this example to R.
Unfortunate, but understood. Looking at the implementation for
Vector, the implementation of the constructor and opAssign look
like it has to copy the data over anyway.

As much fun as it is to figure these things out, I have never
had sufficient time or motivation to do so.
Yeah, that seems like it would be a bit hairy to figure out.
