I'd like to see $-N like you can do with $gettok:
$-1 returns the last token like $gettok($1-,-1,32)
$-2--1 returns the second to last and last tokens like $gettok($1-,-2--1,32)
$-3- returns the third to last token and onwards like $gettok($1-,-3-,32)
Then a suggestion for both $gettok and parameters; maybe allow positive to negative ranges, like this $2--1 and $gettok($1-,2--1,32)
