I think it's fair, though, to say that it's likely that the implementation and/or semantics may be more based on other JVM languages, who have to work on Java's terms.

In particular, I'm talking about the fact that Java doesn't really have "copy types" or "pass by copy" or whatever. So, sure, C has struct, Swift has struct, etc, but Java can't really model its version off of the way those work.
