- The way I read "Definitional Interpreters" pp 178-183 of Stoy, I get

- here means that the fixed point stuff doesn't have unwarranted
- assumptions buried in it. Personally I've always viewed ds
- definitions as interpreters, but then maybe that's why I've never got
- to grips with the finer points :-)
