Range written another language's way

Built from the repository at commit a8614dc.

A range is written a..b, which leaves out b, or a..=b, which includes it. Sisu has no a..<b and no a...b.

Why

.. already leaves out its end in a for loop, so an inclusive .., as some languages spell it, would change the loops that exist; Rust's ..= adds the inclusive form without that. Both work in a for loop and in a pattern. 0..<n means what 0..n means, so the fix deletes the <. 1...5 could mean 1..=5 or 1..5, so the report names both and offers no fix.

Broken

fn main() {
    for i in 0..<3 {
        print(i)
    }
}

What sisu says

error[E0132]: write `0..3`
 --> E0132.sisu:2:15

2 |     for i in 0..<3 {

2 -     for i in 0..<3 {
2 +     for i in 0..3 {

sisu: 1 error

Fixed

fn main() {
    for i in 0..3 {
        print(i)
    }
}
