Hygienic macros are a Scheme thing.  Basically,
traditional macros introduce a form of unmarked dynamic scope (hi
Curt!)  Hygienic macros are supposed to prevent that by lexically
scoping certain variables introduced by the macro.

Yup, I know what they are. I haven't really been bitten by this in Clojure (because I don't write many macros, probably), and I quite often *want* that dynamic scoping, because my macros are basically delaying code evaluation. Clojure has an auto-gensym mechanism that's good enough for rudimentary hygiene. I've listened to a few podcast episodes with Matthias Felleisen explaining Racket's macro system, and it sounds both cool and more complicated than I need. ;)
