This issue is one of the things Perl 6 addresses well in my opinion. Regular ranges include their endpoints, and you can think of ^ as "not including" or "up to (exclusive)" 1..5 is 1, 2, 3, 4, 5 1..^5 is 1, 2, 3, 4 1^..5 is 2, 3, 4, 5 1^..^5 is 2, 3, 4 There's also convenient shorthand for 0..^n (useful if you want to do something n times): ^n
