The issue is that strings aren't input ranges in betterC [1],
due to autodecoding.
Normally you'd work around this using std.utf.byCodeUnit, but
that's currently broken, because std.utf attempts to import
core.exception.UnicodeException from druntime at module scope
[2], causing any betterC

Actually, I kind of prefer the relevant line as
x.byDim!1[0].each!"a -= 2";
which makes it a little clearer that you can easily change [0] to
[1] to apply each to the second column instead.

mir has byDim for something similar (numir also has alongDim).
This is how you would do it:

auto x = [0.0, 1.4,

Thanks for your question, it led me to focus on the Label and now
I've solved the problem.
I thought that onChangeState was never called before the Label
was constructed, but it turns out it is called before. So now I
use:
if (statusLabel !is null)

Other than that, I see nothing wrong here.

Hi Stefan,
I'm sorry to bother you, I just wanted to kindly ask if you would
upload the formatter to ctfeutils on github it would help me alot.
I'm porting a simple game to GtkD to learn the library and more
about D.
Unfortunately, I've hit a show-stopping crash.
I have a subclass of ApplicationWindow which has this method:
private void onChangeState(int score, Board.State state) {
import std.format: format;
