I'm not sure why there's a warning about using an alias. 43.3.1 says
to use them for improved readability.
Mostly because you should just name variables correctly the first time. It improves readability if you use $n parameter names, which you should not. As noted in 43.3.2, sometimes you don’t have a choice, though new and old aren’t usually problematic enough to warrant aliasing.
