As usual I am in favor of more algorithms, provided someone supplies Scheme source.

I'm feeling totally overwhelmed this week. And maybe the next. So I don't know what deadline you are on (I see a 60-day marker in the srfi)

I could volunteer to write a pure-scheme implementation, but despite coding in scheme for a decade, I still code like a novice... I'm fairly certain you'd find my code appalling.

p.s. what the heck ... I can spend the next hour or two, and see what I can come up with. It will be sloppy, and no unit tests...

I just found srfi-194, and would like to request: please please, please a Zipf distribution.

It's not hard ... its useful in machine learning ... I've got C++ code at the URL below ... I have on my endless "todo" list to write a pure-scheme implementation for the guile folks ... but I guess making it part of the srfi would be better. 

Here's the C++ code; it contains a reference to the published algo.
