Yeah, the NativeActivity is I think the only one that doesn't

But I'm personally OK with that; reusing the platform as much as
we can is a strength of D, it doesn't have to be all one thing. A
little bit of Java gives you hooks into the IDE and stuff and
isn't that much work; you can still reuse the majority of a D

yes. I might not get around to it for a little while and it will
very possibly be opt-in with a -version thing (right now I call
it WithClassLoadSupport - creating a class would use the same
code to work with the binary format). But I do want to do it.
Another challenge would be syntax. D does lambdas and anonymous
inner classes... but they probably won't get the magic on them.
It may end up being a helper template, so you'd be like
JavaLambda!InterfaceName( a => whatever );
or something like that. I still need to think more about it.

I plan to address this later too. Probably all return values will
conservatively get the global ref unless you declare it as like
`Manual!T` instead, which then wraps it for you and uses the type
system to determine what needs to be it.
(if you look at the comments of jni.d you can see a lot of my
notes to self about problems and possible future directions. Not
all of them actually work out, but it gives you some view into
what's in my brain.)
