Just getting lots of inlining? That is just my laziness. :-) It is such a small program that 16 passes goes by quickly and I didn't want to spend time looking for the optimal number of passes. I also accidentally forgot the unsafe options that I tried to see how much speedup they would give. ...I did some more testing and it seems that the program doesn't change much after 4 passes. However, there are differences between 1, 2, 3, and 4 passes. -Vesa Karvonen _______________________________________________ MLton mailing list MLton@mlton.org http://mlton.org/mailman/listinfo/mlton
