AFAIK there's no way to specify to use D with an initializer:

You can have explicit constructors:
union Test
{
A a;
B b;
this(A a) {
this.a = a;
}
this(B b) {
this.b = b;
}

Does the following make any difference?

I changed it from this,
const Size DEFAULT_SCALE = { 5, 13 };
to this,
const Size DEFAULT_SCALE = Size(5,13);

Of course you do :) I have honestly no idea what's going on.
So, I guess no one in this forum knows what the D1 error,

But, look at line 7955:

And there is no error for that line. Changing the 5 and 13 for

What if I needed that 5 and 13 there?

In case it helps you or others to answer, the code appears in D2 as well:

D1: Error: duplicate union initialization for size
Greetings.
I know that D1 will be deprecated pretty soon and I have a huge
project based on D1. I am trying to build everything using the
latest D1 build (1.076). I am looking into cleaning up a lot of
code for this project that uses, dbi, juno and dfl. I am finding
this error while compiling the code:

This is line 7634:
