CPL paragraph
The effect of this rule for selecting from a set of classes with no
predecessors is that simple superclass chains and relatively separated
sublattices are kept together in the class precedence list. For example,
let $T\sub 1$ and $T\sub 2$ be sublattices whose only element in common is
the class {\bf T}, let $C\sub 1$ be the bottom of $T\sub 1$, and let
$C\sub 2$ be the bottom of $T\sub 2$. Suppose $C$ is a class whose direct
superclasses are $C\sub 1$ and $C\sub 2$ in that order, then the class
precedence list for $C$ will start with $C$ and will be followed by all
classes in $T\sub 1$; after all the classes of $T\sub 1$ will be all
classes in $T\sub 2$.
