Implementation of R5RS-style define-syntax, let-syntax and letrec-syntax for Common Lisp.

it will require some changes to work in scheme.

But, it doesn't provide hygiene

This Common Lisp implementation does not provide hygiene.

FWIW, my library has sort-of same thing which works on s7/biwascheme(port of chibi-scheme syntax-rules on define-macro without any hygine)

https://github.com/okuoku/yuni/blob/f9f54b09b066c17d02c9a6d634ce08be2ec0e802/lib-runtime/generic/synrules.scm#L159

Personally I'm happy with this(as portability layer so I can re-use existing my scripts on biwascheme, with extreme care) but in general, IMHO, considerable portions of syntax-rules use assume hygiene.

@okuoku interesting project, I'm thinking about adding R5RS functions to my lips in JS (https://jcubic.github.io/lips/), it may be helpful.
