- Anonymous labeling is applied to a :attr:`.func` construct that is
passed to :func:`.column_property`, so that if the same attribute
is referred to as a column expression twice the names are de-duped,
thus avoiding "ambiguous column" errors. Previously, the
``.label(None)`` would need to be applied in order for the name
to be de-anonymized.
fixes #3663
