If true, then there may exist break 'a
values that aim to
break out of this block early. As of this writing, this is not
currently permitted in Rust itself, but it is generated as
part of catch
statements.
recovered: bool

If true, don't emit return value type errors as the parser had to recover from a parse error so this block will not have an appropriate type. A parse error will have been emitted so the compilation will never succeed if this is true.
