[section:boost__mysql__WritableFieldTuple 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
[link mysql.prepared_statements.writable_field_reference 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`.
