No doubt you could explain it more eloquently than I, but this works:

[set listing_counter][/set]
[loop list="1 2 3 4 5 6 7 8 9"]
[loop-last][calc]return 1 if ++$Scratch->{listing_counter} > 1; return 
0;[/calc][/loop-last]
[loop-code] - [scratch listing_counter]<br>
[/loop]

...and this does not:

[loop list="1 2 3 4 5 6 7 8 9"]
[tmp listing_counter][calc] [scratch listing_counter] + 1 [/calc][/tmp]
[loop-last][calc] return 1 if $Scratch->{listing_counter} > 1; return 0;
[/calc][/loop-last]
[loop-code] - [scratch listing_counter]
[/loop]
