gen-interface can extend, does that help at all

definterface wraps gen-interface and also imports, but you could do that. I'm not really sure why they differ here

Thanks, I’d forgotten about gen-interface. There’s not much difference in overhead though, between having to use AOT and using java compilation.

I’ll look at the definterface implementation.

but an ask would be ok too, I can't think of a good reason for definterface not to allow extends
