I have uploaded Will's recent modifications into the official SRFI location. Note that I have also generously extended the draft date for one more month. This is because I'm moving between locales during this time; setting it any sooner wouldn't help because I will almost certainly be without Internet access during that period. I do hope we can get this SRFI sorted out before August 28 so that it can go into final status (if that be its fate) on time. Note that Will has also provided an extensive implementation, which is available via hyperlink from the SRFI document. Cheers, Shriram
