 Discussion on scheme-reports has clarified that implementing `letrec`
 sequentially (i.e. as `letrec*`), which is what Chicken does, is allowed
 by R7RS.  Therefore, for R7RS compatibility, all that is needed is to
 expose `letrec*` as equivalent to `letrec`:

 {{{
 (define-syntax letrec*
   (syntax-rules ()
     ((letrec* bindings . body) (letrec bindings . body))))
 }}}
