Another strange thing is that:

? interface SturdyRef {}
java.lang.RuntimeException: Failed: can't redefine SturdyRef

But I can override it using my loader. I think this is a good thing (I
want to run my unit-tests in an environment with fake SturdyRef objects
that don't really use the network), but I'm wondering if there's some
security reason that means it shouldn't be redefined (auditors, etc)?

Also:

? { interface SturdyRef {} }
syntax error: 
  { interface SturdyRef {} }

But:

? { interface Foo {} }
# value: Foo
