I always liked the idea of slip lanes, as then you could check first for a conflict with a pedestrian (looking left and right), then cross that point and worry about a conflict with a car or bike (looking far left). But some people are now trying to remove them because they're worried they can cause drivers to speed through the pedestrian crossing.
