CombinatorialFreeModule._element_constructor_: Deprecate initialization from a given index #34507
Description
CombinatorialFreeModule._element_constructor_ says this:
Do not rely on the following feature which may be removed in the future::
sage: QS3 = SymmetricGroupAlgebra(QQ,3)
sage: QS3([2,3,1]) # indirect doctest
[2, 3, 1]
Here we actually deprecate it.
