We've already had a suggestion for [[]]@5 and that should deal with that issue. Steven is proposing "multiply by copying" as an alternative to "multiply by referencing", so an alternative multiplication operator should fit that correctly. Steve, I don't want to speak for you; can you confirm or deny acceptance of the matmul operator as a better spelling? ChrisA -- https://mail.python.org/mailman/listinfo/python-list
