\item[cpl] A pointer to an array of pointers to class objects listing all
of the class's superclasses, from most- to least-specific, starting with
- the class itself, so $c@->@|cls|.@|cpl|[0] = c$ for all class objects
+ the class itself, so $@|$c$@->cls.cpl[0]| = c$ for all class objects
$c$.
\item[link] If the class is a chain head, then this is a null pointer;
might or might not be a direct superclass).
\item[head] A pointer to the least-specific class in this class's chain; so
- $c@->@|cls|.@|head|@->@|cls|.@|link|$ is always null, and either
- $c@->@|cls|.@|link|$ is null (in which case $c@->@|cls|.@|head| = c$) or
- $c@->@|cls|.@|head| = c@->@|cls|.@|link|@->@|cls|.@|head|$.
+ @|$c$@->cls.head@->cls.link| is always null, and either @|$c$@->cls.link|
+ is null (in which case $@|$c$@->cls.head| = c$) or $@|$c$@->cls.head| =
+ @|$c$@->cls.link@->cls.head|$.
\item[level] The number of less specific superclasses in this class's
- chain. If $c@->@|cls|.@|link|$ is null then $c@->@|cls|.@|level|$ is
- zero; otherwise $c@->@|cls|.@|level| =
- c@->@|cls|.@|link|@->@|cls|.@|level| + 1$.

+ otherwise $@|$c$@->cls.level| = @|$c$@->cls.link@->cls.level| + 1$.
\item[n_chains] The number of chains formed by the class's superclasses.
\item[chains] A pointer to an array of @|struct sod_chain| structures (see
below) describing the class's superclass chains, in decreasing order of
specificity of their most specific classes. It is always the case that
- $c@->@|cls|.@|chains|[0].@|classes|[c@->@|cls|.@|level|] = c$.
+ $@|$c$@->cls.chains[0].classes[$c$@->cls.level]| = c$.
\item[off_islots] The offset of the class's @|islots| structure relative to
its containing @|ichain| structure. The class doesn't define any slots
\item[classes] A pointer to an array of class pointers listing the classes
in the chain from least- to most-specific. So
- $@<classes>[i]@->@|cls|.@|head| = @<classes>[0]$ for all $0 \le i <
- @<n_classes>$, $@<classes>[0]@->@|cls|.@|link|$ is always null, and
- $@<classes>[i]@->@|cls|.@|link| = @<classes>[i - 1]$ if $1 \le i <

+ $@|@<classes>[$i$]@->cls.link| = @|@<classes>[$i - 1$]|$ if $1 \le i <
@<n_classes>$.
\item[off_ichain] The size of the @|ichain| structure for this chain.
