Thank you for the link! It was very useful.

I've stripped lots of code and now, it seems too simple to not be able
to figure out where the problem lies. I've always thought the error was
related to templates, but as I said; it was much more simple.

Perhaps the problem is obvious for those experienced in D but I am still
a rookie. I've also searched for a solution but I have found none.

struct DVector2
{
	float x, y;
	
	this(float x, float y)
	{
		this.x = x;
		this.y = y;
	}
}

void main(string[] args)
{
	// Creating This Vector Fails
	// 'Error: cannot evaluate __ctmp3.this(0F, 1F) at compile time'
	static immutable DVector2 _test = DVector2(0f, 1f);
	
	// Same with variable within class
	C c = new C;
}

class C
{
	// This code fails as well, with the same error
	immutable DVector2 _test = DVector2(0f, 1f);
}
