Converting between View and Storage is not behaving as expected

This may be an error on my part that I just can't "see through", but nonetheless, it seems possible that there are "gaps" in trait implementations that allow for the expected casting.

When I call `&xs.into()`, I get the following error

```rust
the trait
`From, Dyn, ViewStorage<'_, f64, Const<1>, Dyn, Const<1>, Dyn>>>` is not implemented for
`Matrix>

```

when trying to invoke this function

```rust
fn dot(ws: &DVector, xs: &DMatrix) -> f64 { .. }
```

where
* xs: is an item from the row iterator for `&'a DMatrix`

All in all, I'm sending a `Const` structure (from the iterator) to a function (`dot`) that expects `Dyn`. That seems like a safe cast...

Thank you in advance for clarifying how I should get View to behave like Storage in this scenario. A likely answer is an explanation for why it's unsafe to perform this cast.
