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.) -- Wolfgang Corcoran-Mathe <[email protected]>
