Comment (by SimonKing):
The error disappears if one does not override that `__classcall__` method
of symmetric function algebras. However, by the first ticket, it uses a
weak cache, which results in many errors elsewhere...
But if I recall correctly, there has been a recent ticket dealing with
coercion for symmetric functions. Perhaps a miracle occurs and the
strongly cached custom `__classcall__` can be cancelled (count the words
that start with "c"...)?
