I disagree. If you've progressed beyond the absolute beginner phase you know exactly what that line is when you see it. You've only put in work to obfuscate your code a bit and (potentially) cause conflicts with other units whose author had the same idea.

Provided that he knows about the macro. Otherwise it's slower and if you switch projects often it requires that you remember what's it about.

I guess it could be useful for teams working together on bigger codebases.
