You're welcome. My idea was to start submitting SRFI's that concentrate on small stuff that makes scheme-code unportable and helps implementors avoid reinventing wheels and know what's "standard" but undocumented out there already, rather than major additions to the language. 'Cos to my way of thinking, there's not really much use for a nifty module system or a nifty threading model or whatever, unless the modules are portable between implementations -- and portability these days founders on small stuff like what schemes do with the undefined behaviors of (write).
