We could probably also lint overlapping ranges, but its probably out of scope :D

pub fn main() {
    let x: u8 = 3;

    let b = matches!(x, 0..=1 | 0..=2 | 0..=3);
}

[y21]

Good idea, this now also lints (overlapping) ranges

Bouncing review to @Centri3

Looks good overall, thanks! Just two minor nits from me :D

[y21]

Oh this lint should probably be renamed to manual_range_patterns (note the s)
