They are aliases, but that isn't really how people think of them - or at least not how I think of them anyway. Pass-by-reference is a purpose in itself, and using an "alias type" is in that case just the means. In some languages (e.g. Pascal family), there are no C++-style reference types but pass-by-reference parameters are still supported. | |
