There is a nice convenience method of `get`, that allows to handle out of bounds access with a default value.

```julia
julia> get([1,2],1000,"my default value")
"my default value"

```

Is there something analog for multidimensional indexing? For instance I want to to access a 3x5 matrix and get back `NaN` at index `(100,200)`.

It’s the same.

```julia
julia> get(rand(3, 5), (100, 200), NaN)
NaN

```

Dang, I tried `get(rand(3,5), CartesianIndex(100,200), NaN)` and it did not work :D.

It’s probably an oversight that it doesn’t work. Worth filing an issue about, or even a pull request.
