        The value of a keyword can be a:

        - scalar which is returned as a normal python scalar.
        - an array which is returned as a numpy array.
        - a reference to a table which is returned as a string containing its
          name prefixed by 'Table :'. It can be opened using the normal table
          constructor which will remove the prefix.
        - a struct which is returned as a dict. A struct is fully nestable,
          thus each field in the struct can have one of the values described
          here.

        Similar to method :func:`fieldnames` a keyword name can be given
        consisting of multiple parts separated by dots. This represents
        nested structs, thus gives the value of a field in a struct
        (in a struct, etc.).

        Instead of a keyword name an index can be given which returns the value
        of the i-th keyword.
