Description
For Cartan Types 'A' a problem with the weight function of crystals was described here:
http://groups.google.com/group/sage-combinat-devel/browse_thread/thread/7cdfe075257ba963?hl=en
The method of correcting this problem was to hard-code the weight in the crystals of letters, and to have the crystals of tensors get the weight of a tensor element by summing the weights of its constituents. This alters the weight for Type A (correcting the defect) and returns the same weight as the old algorithm for other Cartan types.
When the patch was implemented it was found to be 2-3 times faster than the old algorithm.
