/// @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 compile error if a type variable is used
/// in static context as a type of a local variable in a static method.
