I have always been puzzled about why simpsum:true didn't already try to call
whatever tools were around to compute a closed form.
Setting simpsum:true (in Macsyma) does the job some of the time, to get a
closed form. But other methods are used only when its version of closedform
is called.
Perhaps it is just that bringing out the big guns of closedform is too
expensive to use?
