/// @description Regression test for the Issue 34741: Analyzer doesn't allow
/// function to use type parameter [<Instance of 'TypeParameterMember'>] as a
/// type argument whereas dart does allow this.
/// @note: after https://github.com/dart-lang/language/issues/496 generic
/// function types as type arguments and bounds are allowed, so there is a error
/// in dart 2.9, but there should not be error in the recent dart versions.
