It is certainly true that not all SRFIs *are* implemented in all Schemes. However, most SRFIs *can* be implemented in all R5RS-compatible Schemes, often trivially. This SRFI (and possibly certain others) *cannot*. The following two examples illustrate the difference: If I write code that uses SRFI-1 and then discover that I want or need to run the code in a Scheme that doesn't implement SRFI-1, I can simply load Olin's reference implementation. If I write code that uses SRFI-55 and then discover that I want or need to run the code in Scheme48, I am hosed. Regards, Alan -- Dr Alan Watson Centro de Radioastronomía y Astrofísica UNAM
