> Select values where a boolean selection array is true. As a default, if any
> values in the selection are null, then values in the output array should be
> null.
> The null behaviour does not need to be toggable, if the user wants to select
> nothing in the case of null, then it is necessary to call
> selection_array.fillna(false) first.
