Structs in D ought to be treated like "glorified ints", as Andrei puts it. If you need complex ctors and complex methods, that's a sign you should be using a class instead.
I prefer not to use classes, as the code would now move towards using references, which is the exact reason I'm using structs.
I ended up creating a constructor for my needs and disabling the default constructor. I'm mostly just surprised the static syntax is turned off by adding one. I still don't see the reason behind it. Why have it but disable it?
I ironically almost always need the exact same constructor with the identical arguments though: Initialize the matrix to the identity matrix. Why not introduce the empty self-defined constructor as a separate thing from the .init value?
On a sidenote, I'm surprised D did not choose 0 as the default floating value. Doesn't almost every language do this? I understand the thinking behind it, but when the type one uses in a template influences the behavior of the code, that seems like a pretty big red flag to me. (Any non-floating type defaults to 0, but using floats/doubles suddenly introduces NaN, surely I'm not the only one that sees a problem with this 😅) Especially when it's basically a standard 0 is used for this. Sorry for the rant.
