 If $T$ is a deferred type with prefix $p$, then if $p$ has not been successfully loaded, a dynamic error occurs.

-If $T$  is malformed or if $T$ is a type variable a dynamic error occurs. In checked mode, if $T$ or any of its superclasses is malbounded a dynamic error occurs.

 A fresh instance (\ref{generativeConstructors}), $i$, of class $R$ is allocated.
 Then $q$ is executed to initialize $i$ with respect to the bindings that resulted from the evaluation of the argument list, and, if $R$ is a generic class, with its type parameters bound to $V_1 \ldots V_m$.

 The invariant that each normative paragraph is associated with a line
 containing the text \LMHash{} should be maintained.  Extra occurrences
 of \LMHash{} can be added if needed, e.g., in order to make
 individual \item{}s in itemized lists addressable.  Each \LM.. command
 must occur on a separate line.  \LMHash{} must occur immediately
 before the associated paragraph, and \LMLabel must occur immediately
 after the associated \section{}, \subsection{} etc.
