Wouldn't that depend on the scripting language? But you can 
control layout of structs and might be able to print out other 
information you need using reflection, so you might be able to 
create the stubs you need using traits and properties?

The gc accepts foreign root pointers, but the gc itself might be 
too slow. So you would rather use v8s gc and @nogc in D?
