   @zeroshade For example, for conversion libraries that follow a visitor pattern and walk through a columnar data tree generating builders for each column as they go. The output of this visitor will be a list of builders and field definitions. Starting from a builders tree (provided by NewStructBuilder) is not easy to integrate with this type of pattern.
