But actually, if you're aiming for R7RS support then

string-map is in (scheme base).  Just replace the

cond-expand with:

(import (scheme base))

Hmm... sadly, (import (scheme base)) fails with Chicken and Gauche. I am also having a hard time figuring out how to print with Chibi. I tried the manual, and I tried (print), (printf) and (display).

Then change your cond-expand to:

(cond-expand

 ((or chicken gauche)  ; compatibility

  (use srfi-13))

 (else                 ; R7RS

  (import (scheme base) (scheme write))))

R7RS puts display in (scheme write), because it typically

falls back to write for non-char/strings, and because write

is actually a fairly large and complicated procedure not

needed by most libraries.

However, write-char, write-string and newline are all in

(scheme base) so you could just use write-string here.

You can also (import (scheme r5rs)) to get all of the R5RS

bindings except transcript-on/off.
