-
-        `self`: represents the annotation of the current parameter to infer the

-            `Iterable[_T]` of the `iterable` parameter and then, when recursing,

-
-        `value_set`: represents the actual argument passed to the parameter
-            we're inferrined for, or (for recursive calls) their types. In the
-            above example this would first be the representation of the list
-            `[1]` and then, when recursing, just of `1`.
-
-        `is_class_value`: tells us whether or not to treat the `value_set` as
-            representing the instances or types being passed, which is neccesary
-            to correctly cope with `Type[T]` annotations. When it is True, this
-            means that we are being called with a nested portion of an
-            annotation and that the `value_set` represents the types of the
-            arguments, rather than their actual instances. Note: not all
-            recursive calls will neccesarily set this to True.
