[ that starts a line inside brackets

Built from the repository at commit a8614dc.

Inside ( or [, a [ cannot start a line that follows an expression.

Why

Inside brackets a line break does not end the expression, so a [ at the start of the next line would silently index the line above. Sisu rejects it: add a comma if the [ starts a new element, or put it on the line of the array it indexes.

Broken

fn main() {
    let grid = [[1, 2], [3, 4]]
    print(grid
    [0][1])
}

What sisu says

error[E0005]: `[` cannot start a line here

  = help: add a comma, or put `[` on the line of its array

Fixed

fn main() {
    let grid = [[1, 2], [3, 4]]
    print(grid[0][1])
}
