I assume Richard will explain this since this is his opinion.
Certainly explicitly calling ev is tricky since evaluation may happen in
the wrong scope
(I struggled with this in levin). I.e. the expression given by the user
may contain names of local variables
or parameters. In his earlier emails Richard seemed to impy that one
could get by without ev and
replace it by substitution. I was just testing this.
