I agree, although SRFIs can, of course, specify procedures that can’t
be portably implemented.

If John thinks this polymorphism is a bad idea, then I’ll withdraw the
suggestion.  It was a spur-of-the-moment idea that came to mind when
I read the spec. for ‘lazy-and-procedure’.  (I’ve thought that Scheme
needs more convenient lazy-evaluation tools for a while now, however.)
