Every object is a \emph{direct instance} of exactly one \emph{class}. The
class determines which slots its instances have, which messages its instances
-can be sent, and which methods are invoked when those messages are received.
-The Sod translator's main job is to read class definitions and convert them
-into appropriate C declarations, tables, and functions. An object cannot
-(usually) change its direct class, and the direct class of an object is not
-affected by, for example, the static type of a pointer to it.

If an object~$x$ is a direct instance of some class~$C$, then we say that $C$
is \emph{the class of}~$x$. Note that the class of an object is a property
