(en) Marc Feeley, « Implementors' intentions concerning R6RS », sur lists.r6rs.org, (consulté le ) : « It seems clear to me that few Scheme implementors have the intention to modify their implementation to support R6RS fully. Generally each implementor intends to pick and choose minor R6RS features that will be supported (but not the same set of features for all Scheme implementations). For this reason I believe that R6RS will fail to achieve its goal of allowing the sharing of code between different Scheme subcommunities. We need to start working on a standard that will. ».
