Maybe I don't understand the subject very well, but shouldn't backtracking from the choice of implementing M:N simply involve limiting it to 1:1, and turning off the code that emits yield statements? Thus making actual benchmarking possible. While that will cost the work to implement it still; Clearly that should be worth getting the actual performance data, right? Indy
