/**
 * @assertion  A type T is malformed iff:
 * • T has the form id or the form prefix.id, and in the enclosing lexical scope,
 *   the name id (respectively prefix.id) does not denote a type.
 * • T denotes a type variable in the enclosing lexical scope, but occurs in the
 *   signature or body of a static member.
 * • T is a parameterized type of the form G<S1, ..., Sn>, and G is malformed.
 * • T denotes declarations that were imported from multiple imports clauses.
 * Any use of a malformed type gives rise to a static warning. A malformed
 * type is then interpreted as dynamic by the static type checker and the
 * runtime unless explicitly specified otherwise.
 * @description Checks that it is a static warning if a type variable is used in static context.
