in reply to Variance in sort order (collation) {Solved: needed sharper eyes}

There does seem to be a problem in multiple keys sort: 
    $last[$a] cmp $last[$b]
    or
    $first[$a] cmp $last[$b]

[download]
should be: 
my @index = sort {
    $last[$a] cmp $last[$b]
    or
    $first[$a] cmp $first[$b]
} 0 .. $#first;

     sort on multiple keys
Adler, Rich
Jackson, Jon
Jones, Fred
Jones, John
Smith, Joe
Smith, John

      But, testing, single sort (cmp):
     Fred
     Joe
     John
     John
     Jon
     Rich

    Bingo! Thank you, tangent!

    and apologies to all the little electrons I inconvenienced by my bleary-eyes ...to say nothing of the Reverend Monks.
