Moving this from the "Differences from other Lisps" thread instead of hijacking it:

> Racket allows non-hygienic macros which still maintain hygiene except where explicitly broken since identifiers have an associated scope that can be set. I think R6RS also has this, but I don't think it is quite as powerful as Racket's macro system.

Cool, I wasn't aware of that. I have a couple of non-hygienic macros that work by shuffling things back and forth with datum-\>syntax and syntax-\>datum, but that has always seemed clumsy. What is the right way to do it?

I think @ryanc gives a good explanation here

I hope the link works - it is dated 23 Jan 2020 if it doesn’t it should be visible via the archives at [https://lists.racket-lang.org/](https://lists.racket-lang.org/)

Very nice. Thanks, Stephen.
