/// @assertion The exact result of an `augmented` expression depends on what is
/// being augmented, but it generally follows the same rules as any normal
/// identifier:
/// - Augmenting getters: Within an augmenting getter `augmented` invokes the
///   getter and evaluates to the return value. If augmenting a field with a
///   getter, this will invoke the implicit getter from the augmented field.
///
/// @description Checks that it is not an error to invoke operator `+` on return
/// value of `augmented` expression if its return type has a `+` operator
/// @author sgrekhov22@gmail.com
