So, is RENAME closed upon  the environment in which ER-MACRO-TRANSFORMER
is called?  So I can do something like:

(module (for-expand)
    (the-transformer)
  (import (scheme)
          (chicken syntax))
  (define (the-transformer input-form.stx rename compare)
    (define %fx+ (rename 'fx+))
    ---)
  #| end of module |#)

(module (for-runtime)
    ()
  (import (scheme)
          (chicken syntax)
          (chicken fixnum))
  (import-for-syntax (scheme)
                     (for-expand))
  (define-syntax the-macro
    (er-macro-transformer the-transformer))
  #| end of module |#)

and  RENAME  will  cleanly  pick  FX+  from  the  environment  in  which
ER-MACRO-TRANSFORMER has been called?

  I'm  not  trying   to  inject  syntactic  bindings   in  the  original
environment, I just want to put as much as possible of a macro body into
a separate library to be imported "for syntax".
