Just read the latest draft of SRFI 170. I like the way the spec is going. Especially happy with the simplicity of the timespec section now. Thanks for the continued effort John and Harold! One thing that still puzzles me is exec-path-list. It's a variable that mirrors the value of the PATH envar, but "changing the value of PATH may or may not not change the value of this variable" so you can't trust it when reading it. What are the intended applications of this variable?
