> In CustomEvent, History, MessageEvent, PaymentMethodChangeEvent, and
> PaymentResponse, we have custom bindings support for representing attributes
> of type object or any.
> 
> These custom bindings tend to do two things:
> 
> 1. Add a custom getter for an attribute of type object or any that converts
> the native value to a JSValue, cache that JSValue in a
> JSValueInWrappedObject in the wrapper class, then return the cached JSValue.
> 2. Add a custom mark function that visits the cached JSValueInWrappedObject
> as well as any other JSValueInWrappedObjects in the wrapper class.
> 
> We should teach the bindings generator to do this for us for attributes of
> object or any type (perhaps with a custom annotation).
