Blargh it was supposed to just work without main() on the new ldc 
but I only actually ran stuff with 1.19 on actual android.

What does the android studio debugger say about it? Missing 
method or another link problem?

Yeah, it uses a private name and registers that in a static 
module constructor (this allows it to support overloads more 
easily), so that specific name not being there isn't wrong, but 
it could be the registration function never got called again.


sorry I've been so unresponsive on all this, I've had a lot other 
surprise/emergency stuff going on irl so I'm barely keeping up 
with my email.
