I would like to see the reference implementation to be improved for efficiency. Yes, I know that efficiency is not a requirement for SRFI reference implementions. But many Scheme implementors just copy the reference implementation without modifications in order to save time - which is understandable but bad for many users. I found only one improvement - but others might be more clever - last 2 lines: (lambda (l alist) (display (apply string-append (reverse l)))) Should not we avoid constructing the result as a string and write something like this: (lambda (l alist) (let iter ((l2 l)) (cond ((pair? l2) (iter (cdr l2)) (display (car l2)))))) Greetings Sven P.S. Thanks Ray Dillinger and Al Petrofsky for this draft SRFI!
