You're using an inclusive upper range here. Not that that's necessarily wrong, but it isn't standard for the reason Dijkstra mentioned (how many fingers do I have? 5 - 1 = 4. Oops.)
Congratulations; you have successfully introduced a whole new way to have off-by-one errors.
People are used, due to forty years or more of tradition in the great majority of major languages, to zero-based indexing. Tossing that away Because It's Inelegant won't do much good to anyone, especially when you take into consideration the fact that an awful lot of math is more convenient with 0-based indexing.
for(i in [1..5]) print finger[i]
