/// re-exported symbols retain their migrated status (that is, downstream
/// migrated libraries will see their migrated types).
/// @description Check that if generic function typedef with nullable type
/// parameter is exported from opted-in library to legacy library and then back
/// to the opted in code, typedef retains its status. Typedef is in the form
/// [typedef <type> <identifier> <formalParameterPart>]. Check function with
/// return value.
