         Branch:                     |  caching scheme, it can crash for
  public/combinat/integrable-15806   |  hard computations. Obviously this
   Dependencies:                     |  should be fixed. Not all docstrings

Comment (by bump):

 With the last commit inner products are implemented for (x|y) in three
 cases: when x and y are both elements of the root lattice, when one is in
 the root lattice and the other in the weight lattice, and when both are in
 the weight lattice. This code could be moved to
 `root_lattice_realizations.py` and `weight_lattice_realizations.py`
 addressing the problem in #18034.
