#### WritableField and WritableFieldTuple concepts

A type is a `WritableField` if it can be used to represent a statement parameter value to be sent to the server. A type `T` satisfies `WritableField` if it is any of the types listed in this table. More types may be added in future releases.

A type `T` is a `WritableFieldTuple` if it's a `std::tuple` specialization, or a reference to one, and all element types fulfill `WritableField`, or are (possibly cv-qualified) references to `WritableField` types. Empty tuples satisfy `WritableFieldTuple`.
