1. request for comments- strtok
For sorttok(), a negative sort parm as an atom currently reverses the sort,
like this:
s = {"a b a a","a c a a"}
s = sorttok(s,-2,32)
s now= {"a c a a","a b a a"}
but i can't use this syntax to spec sorting on the 2nd token from the right.
What would you do?

Kat,
the problem with this is that you are using one parameter to specify two
things : element and direction. You would be better off using two
parameters. Actually you might consider three parameters: Element,
Direction, and Relativity. And as these are always used, you could put them
in a sequence so that you can specify multiple sort keys.
-- Sort 's' in descending order using the 2 from the end as the key.
sorttok(s, {{Descending, 2, FromEnd}})
-- Sort 's' first element ascending and last element descending.
sorttok(s, {{Ascending, 1, FromStart},{Ascending, 1, FromEnd}})
