Defmacro isn't hygienic, while syntax- is. Is there way to use arbitrary names in hygienic syntax- macros?

If you know the name ahead of time, syntax parameters[1] (if your scheme supports them) work well. syntax-case lets you break hygiene to insert new names in a controlled fashion (but has issues with names known ahead of time; see linked paper). Renaming macros do too, I believe.

syntax-case can introduce arbitrary bindings using datum->syntax.
