Dry and wet objects distinguishable by their prototype

If wrapping a (plain empty) object in a membrane, dry and wet objects have different prototypes. Besides being distinguishable through `Object.getPrototypeOf`, they usually are logged as different strings. Example with the Node.js REPL:
```js
> wet
{}
> dry
rv {}
```
Is there any option I can pass to the membrane constructor to smooth this difference, or is this inevitable?
