I'm not sure the syntax extension specific items are good if the intent is to present this as an argument for moving to Rust from some other language for building such a framework. I'm a bit biased: I'd avoid using syntax extensions that aren't part of the standard, because it adds a point of friction for novice and seasoned Rust developers alike.

Are you talking about the route specification syntax? It doesn't seem much worse than say flask.

In this specific case, yes those particularly would be an example.

But I don't mean in comparison to other languages or frameworks, I mean in generally, as in, I'd avoid creating syntax extensions or using them in any project.

i understand your argument but if you look at <https://news.ycombinator.com/item?id=13246361>, it seems clear to me the use of syntax extensions created an awesome developer experience that would be otherwise impossible (sure you could use the built in typesystem but then you wouldn't have human readable routes in the source)
