2.33.6 Acknowledgements

I am grateful to the members of the Northeastern University Programming Research Laboratory and PLT (and their intersection) for discussions during the pre–draft development of this SRFI and the library that preceded it. We are all indebted to Okasaki for his elegant solution to this problem. Much of the specification is adapted from text intended to belong to the Scheme community; I thank the editors and authors of the RnRS series collectively for their efforts. I am grateful to Donovan Kolbly for serving as SRFI editor and to Taylor R Campbell, Robert Bruce Findler, Aubrey Jaffer, Shiro Kawai, and Alexey Radul for discussion during the draft period. I thank William D Clinger, Robert Bruce Findler, and Abdulaziz Ghuloum for help writing the implementations of quote specific to Larceny, Ikarus, and PLT, respectively. Support was provided by the National Science Foundation under Grant #0937060 to the Computing Research Association for the CIFellow Project.
