To avoid confusion. I was not suggesting to make levin a global default!
It should
only happen after "load(levin)".  I was asking for tips on  how to 
achieve this
(***if*** it is consistent with maxima behaviour, which Richard seems to
think it is not,
but I am not convinced yet).

As I said I don't like this. But I would like

simpsum:closed_form

which would invoke closed_form by default.
