OK. Can you show how you would like to work with such objects?
I'd like to see what you would consider a convenient, natural
notation for working with Lie groups. What are some operations
you'd like to represent?
I gather that, among other things, you'd like to have two or
more Lie groups to work with at the same time.
What is a notation that can distinguish them?
