It's not a matter of confusing them - the problem is that the difference doesn't jump out at you. If you had been scanning a log of all 0's and a 1 jumped out, you couldn't possibly have missed it, and then would have looked up to see which implementation generated it. -- Alex _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
