 ### Return value
 
 The return value of the function may optionally be validated against its return type annotation.

-The following names may not be used by arguments since they can be used internally to store information about
-the function's signature:
-
-* `v__args`
-* `v__kwargs`
-* `v__positional_only`

-These names (together with `"args"` and `"kwargs"`) may or may not (depending on the function's signature) appear as
-fields on the internal Pydantic model accessible via `.model` thus this model isn't especially useful
-(e.g. for generating a schema) at the moment.

-This should be fixable in future as the way error are raised is changed.
