A previous update forced the T under Object<T> to implement UpcastObject<dyn Any> to be able to print it.
However, this trait was never implemented on objects. Arrays can be converted to objects but it's not possible to cast them down to arrays again, because arrays are traits in Rust (dynamic pointers).
Until we wrap arrays with a newtype to cast them back to a regular struct, we can fix the Dafny runtime so that they are still printed as "object"
Second, modify-field!() at the end of a block was triggering parsing issues. I added a block wrapper in the macro to prevent that issue.
How has this been tested?
Two tests added in the runtime.
