Because CTFE is clearly turing-complete, you can express that in
a D

Is there a "best practice" of what the source folder should be

`if(is(T == E[], E))` or `isDynamicArray!T` is you `import

Usually I don't deal with null because my functions get primitive

I don't think this is part of the standard library.

Why is this happening? Does anybody know?

Here you set data[0].y to 0
tempb = data[x].y;
In the first iteration, this equals data[0].y which
