Arrays.

{{alias}}( dtype )
    Returns an accessor function for retrieving an element from an indexed
    array-like object.

    An accessor function accepts the following arguments:

    - arr: input array.
    - idx: element index.

    If provided an unsupported `dtype`, the function returns a default accessor
    function for accessing elements from any indexed array-like object.

    Otherwise, the function returns an accessor function which should *only* be
    provided an array instance corresponding to `dtype` (e.g., if `dtype` is
    'float64', the returned accessor function should only be provided instances
    of Float64Array).

    Accessor functions do *not* verify that provided input arrays are array
    instances corresponding to `dtype`, as doing so would introduce performance
    overhead. If array instances corresponding to other data types are provided
    to an accessor function, JavaScript runtimes will consider the function
    polymorphic, potentially triggering de-optimization. In order to ensure
    maximum performance, *always* ensure that an accessor function is
    monomorphic.

    Accessor functions do *not* perform bounds checking.

    Parameters
    ----------
    dtype: string
        Array data type.

    Returns
    -------
    f: Function
        Accessor function.

    Examples
    --------
    > var f = {{alias}}( 'generic' );
    > var v = f( [ 1, 2, 3, 4 ], 2 )
