You might try something like this:

(##namespace ("foo#"))

(##define-macro (quasiquote x) (##namespace ("" display quasiquote)) (display "called quasiquote\n") `(let () (##namespace ("" quasiquote)) (quasiquote ,',x)))

I'm not sure it solves your specific problem though.

Hello

I've noticed that one cannot refer to builtin syntax using fully qualified notation (something like foo#quasiquote isn't defined; so builtin syntax is present in every namespace but not accessible with any full qualification) and one thus cannot write macros substituting the builtin syntax with something else and then still call the original syntax in the generated code:

(define-macro (quasiquote . l) (display "quasiquote called\n") `(quasiquote ,@l))

`1 => leads to infinite loop, and there's no apparent way around that.

Additionally, this loop cannot be terminated by hitting ctl-c, which means the whole process has to be terminated.

Is there a way to write the above quasiquote wrapper so that it works?
