	Should cut work this way?
	4 points by garply 5194 days ago \| 1 comment
	(cut "ab" 0 10) throws an error, whereas I expected it to take as many characters as possible up to 10. Is there a different function that works this way? Do you think cut should work this way?

Arguably, no. cut uses firstn on lists, which works how you expected it to behave for strings, which is inconsistent.

  arc> (firstn 10 '(a b))
  (a b)
  arc> (cut '(a b) 0 10)
  (a b)
  arc> (cut '(a b) 200 10)
  nil

Of course, cut could just throw errors for out-of-bounds list indices, too.
