Example in section "standard-library/readers-and-writers" does not compile.

[yeah-boi]

One of the examples in the section "standard-library/readers-and-writers" contains the following function:

fn nextLine(reader: anytype, buffer: []u8) !?[]const u8 {
    var line = (try reader.readUntilDelimiterOrEof(
        buffer,
        '\n',
    )) orelse return null;
    // trim annoying windows-only carriage return character
    if (@import("builtin").os.tag == .windows) {
        return std.mem.trimRight(u8, line, "\r");
    } else {
        return line;
    }
}

This does not compile. var line should be replaced with const line.
