Hi There, Runsnake (thanks Nicolas !) just told me that some code spent 90% of its time constructing families. The reason is that to construct elements of a CombinatorialFreeModule the code goes through self.basis() and that the method basis is *not* cached. Since families doesn't have UniqueRepresentation the initialisation code is executed many times... I know that it should written using monomial, but the original writer of the code didn't because the example always construct element using the basis. I think that unless you want to achieve ultimate speed this is a perfectly reasonable ways to write it. So the question is:
Is there any reason why not having CFM.basis() cached ? Note adding the cache still passes the tests !
