suggestion for left() right()

input

"(one,two)"

output

"two"

instead of having to do:

left(tokenat(line,1,","),len(tokenat(line,1,","))-1)

it would be nice to just type:

right(tokenat(line,1,","),-1)

so- basically allow negative numbers for left() right() in case we want all text instead of front or last N characters.
