@feeley I played with define-library a bit and figure out a way to make it work with syntax-case / macro.

Let me know if anything could be improved!

Thanks

Hi. Can you explain how your code works? It seems to avoid preprocessing the macro definitions, in other words the syntax-rules and syntax-case forms are passed through without modification.

i added define-runtime-syntax for syntax-case / syntax. syntax-rules is already a runtime syntax.

(syntax-rules ...) -> (syn#syntax-rules-form-transformer ...) -> #'(##lambda (##src) (syn#apply-rules 'crules ##src))

ping? you might run tests to ensure it's working
