> There is a function {{type()}} that returns the type of a post-bind {{Expression}} as a {{std::shared_ptr<arrow::DataType>}}:
>  [https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/exec/expression.h#L105]
> It would be convenient to also have a function {{type_id()}} that returns this as an {{arrow::Type::type}}.
