The solution is to use wrapper objects with differentiable getter/setter methods (and we should provide a few such objects in the stdlib). Fixes: #3289 This is a potentially breaking change: User code that was previously working with global variables of a differentiable type will now throw an error (previously the gradient would be dropped without warning). The solution is to use `detach()` to keep same behavior as before or rewrite the access using differentiable getter/setter methods.
