This is a good change, thanks @abreis.
I think adding scalar equivalents to functions where we've previously
converted scalars to arrays, ties us up in the future.
The C++ implementation solves this issue by using a `Datum` that's loosely:
```rust
enum Datum {
Array(ArrayRef),
Scalar(ScalarRef)
}
```
This would allow us to avoid `{kernel}_scalar` for all our kernels where 2
or more arrays are currently taken as inputs.
What are your thoughts @jorgecarleitao @alamb @andygrove @ritchie46?
