        Both `base` and `override` are converted to dictionaries if possible.
        Sets are converted to dictionaries with the sets entries as keys and
        Ellipsis as values.

        Each key-value pair existing in `base` is merged with `override`,
        while the rest of the key-value pairs are updated recursively with this function.

        Merging takes place based on the "union" of keys if `intersect` is
        set to `False` (default) and on the intersection of keys if
        `intersect` is set to `True`.
