That's a pretty weak reason to hate macros, frankly. Seems more like a deficiency in the formatter than in the language feature.

As a side note, there's a poorly-documented behavior where rustfmt will format macros that are wrapped in {} if it's valid rust code. So you can even point the blame on tokio for not using formatter-friendly macros.

I agree, that is a weak reason to dislike macros.

I dislike them primarily because of the additional complexity they add that isn't always justified. All of the more complex macros I wrote I regret, especially the one I did at my last job since now others had to maintain it.

Some macro use can be justified, eg serde. But I try to avoid using proc macros where I can (and certainly never try write one anymore)
