{{alias}}( value )
    Returns an array of an object's own and inherited writable symbol
    properties.

    Property order is not guaranteed, as object property enumeration is not
    specified according to the ECMAScript specification. In practice, however,
    most engines use insertion order to sort an object's properties, thus
    allowing for deterministic extraction.

    If provided `null` or `undefined`, the function returns an empty array.

    Parameters
    ----------
    value: any
        Input value.

    Returns
    -------
    symbols: Array
        List of an object's own and inherited writable symbol properties.

    Examples
    --------
    > var obj = {};
    > var desc = {};
    > desc.configurable = false;
    > desc.enumerable = false;
    > desc.writable = true;
    > desc.value = 'boop';
    > var sym = ( {{alias:@stdlib/symbol/ctor}} ) ? {{alias:@stdlib/symbol/ctor}}( 'beep' ) : 'beep';
    > {{alias:@stdlib/utils/define-property}}( obj, sym, desc );
    > var symbols = {{alias}}( obj )
