        # The user/library-level interface is a list of two-column matrices,
        # e.g. 'list(cbind(1,2), cbind(3,4))'. Input to this function is marked
        # as a list of array of numeric.
        #
        # The autogen code generates a check that the list slots must be R6
        # classes; in fact they must *not* be.
        #
        # Here we flatten the list of two-column matrices elementwise to a list
        # of even-length vectors (start end start end start end ...), then
        # serialize them to a language-independent JSON representation like
        # '[[1,2],[3,4]]'. (The same is done in Python by the TileDB-Cloud-Py
        # library.)
        #
        # Context: some items in the TileDB R array UDF API are encoded as
        # R-serialized and shared between the client (us) and the server-side
        # UDF-executor R code, with zero inspection by the REST-server code:
        # e.g. the UDF code itself, and the results. The query-ranges, however,
        # are also decoded and processed by the REST server itself -- hence the
        # particular and careful language-independent handling for query
        # ranges.
