forked from VimPlug/jedi
In 23.1.0 (specifically in 46053d703d)
the definition of the `frozen` decorator was tweaked slightly, such
that its type stub is separate from that for `define`. This means
that Jedi needs to be told about it as a separate member.
I've manually checked that this still works with the prior version
of `attrs`.
