There are currently two built-in set types, :class:`set` and :class:`frozenset`.
The :class:`set` type is mutable --- the contents can be changed using methods
like :meth:`~set.add` and :meth:`~set.remove`. Since it is mutable, it has no
hash value and cannot be used as either a dictionary key or as an element of
another set. The :class:`frozenset` type is immutable and :term:`hashable` ---
its contents cannot be altered after it is created; it can therefore be used as
a dictionary key or as an element of another set.
like :meth:`add <frozenset.add>` and :meth:`remove <frozenset.add>`.

There is no frozenset.add().

Because set and frozenset are documented together, there is no cross-reference target for set.add, it is labelled as frozenset.add instead. This link goes to the correct place.

But this is a wrong name for anchor. We should do something with this.

I agree. I plan to fix it, but it requires changes (& a release) of Sphinx. This PR makes the reference link to the right place, and more importantly means that no future reference errors can be introduced into stdtypes.rst.

Once it is fixed, I plan to go back and update here & a few other places where we have used a different target to the intended one.

Now, I think that we should reorganize the set/frozenset documentation in the way similar to the sequence or bytes/bytearray documentation.

  1. Dedent method descriptions and add class name prefixes. E.g.:
    .. method:: frozenset.isdisjoint(other, /)
                set.isdisjoint(other, /)
  2. Move operators to separate tables. This may wait.

Wrong reverence to remove().

Since it is mutable, it has no hash value and cannot be used as
either a dictionary key or as an element of another set.
The :class:`frozenset` type is immutable and :term:`hashable` ---
its contents cannot be altered after it is created;
it can therefore be used as a dictionary key or as an element of another set.

Non-empty sets (not frozensets) can be created by placing a comma-separated list
of elements within braces, for example: ``{'jack', 'sjoerd'}``, in addition to the
