the standard dialect. The extra defined types are specific to TensorFlow: `QINT`
types like !tf_type.qint8 (etc), `QUINT` types like !tf_type.quint8, all of the
`REF` types like !tf_type.uint8ref, as well as !tf_type.string,
!tf_type.resource, and !tf_type.variant which correspond to the tensorflow types
of the same name.

### Example:

Below is an example of a function operating on the TensorFlow dialect:
