Hi, I'm trying to use defaccessor to set a getter and setter, any idea if I'm doing something obviously wrong here?
#[test]
fn defaccessor_with_closure() {
let state = ::State::new(::JS_STRICT);
state.newobject();
state.newfunction(|js| {
js.pushnumber(42.0);
}, "getter", 0);
state.newfunction(|js| {
js.pushundefined();
}, "setter", 1);
state.defaccessor(-3, "test", ::PropertyAttributes::empty());
state.getproperty(-1, "test");
} thread 'tests::defaccessor_with_closure' panicked at '"TypeError: not a __RustClosure__"', src/lib.rs:243:8

I''m still digging through it but in the call to js_touserdata the object at the top of the stack has a tag of "\001" and the type is userdata.
