/// @assertion An abstract instance variable declaration D is treated as an
/// abstract getter declaration and possibly an abstract setter declaration. The
/// setter is included if and only if D is non-final. The return type of the
/// getter and the parameter type of the setter, if present, is the type of D
/// (which may be declared explicitly, obtained by override inference, or
/// defaulted to dynamic). The parameter of the setter, if present, has the
/// modifier covariant if and only if D has the modifier covariant

/// @description Checks that declaration
