        public Sort mkAbstractSort​(SortKind kind)
        Create an abstract sort. An abstract sort represents a sort for a given kind whose parameters and arguments are unspecified. The SortKind k must be the kind of a sort that can be abstracted, i.e., a sort that has indices or argument sorts. For example, SortKind.ARRAY_SORT and SortKind.BITVECTOR_SORT can be passed as the SortKind k to this method, while SortKind.INTEGER_SORT and SortKind.STRING_SORT cannot.
        Parameters:
        kind - The kind of the abstract sort
        Returns:
        The abstract sort.
        Note:
        Providing the kind SortKind.ABSTRACT_SORT as an argument to this method returns the (fully) unspecified sort, often denoted ?., Providing a kind k that has no indices and a fixed arity of argument sorts will return the sort of SortKind k whose arguments are the unspecified sort. For example, mkAbstractSort(ARRAY_SORT) will return the sort (ARRAY_SORT ? ?) instead of the abstract sort whose abstract kind is SortKind.ABSTRACT_SORT., This method is experimental and may change in future versions.
