  icomment: Branch for lazy load of clock ([04742d889c]) illustrates the possible
            win of changeover for single namespace/ensemble to on-demand load,
            where the performance win is ca. 200 µs/#.  The switch of further
            subsystems to lazy loading may reduce interpreter creation time to ca.
            1000 µs/# what would be almost double as fast than current 8.6 (and
            tipple as fast than current 9.x).

            However, as already said, it'd expect at least
            [../tips/doc/trunk/tip/689.md|TIP#689 (namespace unknown)], and some
            of the subsystems also further improvements, that may help to load
            namespace on demand by any access (e. g. on variable or on namespace
            resolution).
