an anti-clockwise
one-way system is superior (because drivers have better visibility when
curving to the left).

There might be better visibility once in the square, curving to the left, but
surely with traffic going clockwise, entry TO the roundabout, square or
whatever is much easier than if the traffic were coming from the left, since
visibility is better to the entering driver, sitting on the right, if traffic
is also coming from the right.

That same logic is why, presumably, in countries where traffic drives on the
right, roundabouts etc. are anti-clockwise.

In sharp contradistinction to this, have you witnesses the complicated traffic
signalling etc. needed where there ARE anti-clockwise roundabouts in the U.K.?
I am thinking particularly of Hammersmith (and now Vauxhall) Bus Stations. The
Hammersmith entry/exits are particularly tortuous, and several people have been
knocked down (I think one may have died) when trying to walk across the
Southern entry/exit lanes on Hammersmith Broadway (i.e. parallel to the
flyover) because of the odd direction of those lanes, which are opposite to the
way you would expect traffic to travel.

This is exactly right. Having driven my UK car(s) extensively
in Europe for the last three years, by far the hardest thing to do
in such a car is filtering right out of a minor road into a major
one. It's OK if you come to a stop at 90 degrees, but if the road
is wide enough so that you stop at a 60 degree angle your visability
of the traffic already on the road is close to zero without turning
your head into very akward position. Such a road design would
not last very long before it were changed back IMHO.

If London squares are configured as clockwise roundabouts, it allows the
normal "give way to traffic on your right that's already on the roundabout"
rule to be used; otherwise a contrdictory, counter-intuitive rule would have
to be used in those circumstances: hence there woudl be the need at every
junction to think "Is this a clockwise roundabout or an anticlockwise one?
Do I give way to traffic on my right or on my left in this specific case".
Better to have one rule for all situations.

A square is not a roundabout. When you are entering a square, it doesn't
look like a roundabout. It looks like a T-junction between three one-way
roads, like the other million T-junctions between three one-way roads in
central London. A quick glance at a map suggests that, excluding the
squares, these junctions are split 50:50 between those where you must turn
right and those where you must turn left.

Not at all: it is because, when the roads are two-way, this removes
conflicting motions between cars entering and leaving at the same side road.
