There are multiple Scheme implementations that implement SRFI-245 semantics. Are there any that implement SRFI-251 semantics? Or planning to? Is there any user demand for SRFI-251 semantics as opposed to SRFI-245 semantics? Are there any benefits to SRFI-251 semantics over SRFI-246? Does SRFI-251 allow recursive procedure definitions in a body? (SRFI-245 does.) Is SRFI-251 is more true to "the Scheme nature"? As I see it, the answer to all of these questions is "no". -- --Per Bothner xxxxxx@bothner.com http://per.bothner.com/
