Comment:

 Now the second patch has been updated as well. As I have announced, the
 second patch is now not only introducing a strong custom cache for
 `SymmetricFunctions`, but also for the different representations, i.e.,
 for `SymmetricFunctionAlgebra_generic`. It is certainly not ideal that
 symmetric functions need to be strongly cached, but I think that there may
 be a different ticket to resolve this special case.

 Anyway, with sage-5.0.beta13 plus #715, #11521, #12313, #11943, #11935 and
 the two patches from here, all doctests pass. I am confident that they
 would also pass when one only has 5.0.beta13 plus the two patches from
 here.

 Needs review, then!
