Thanks, that's the kind of feature I'm looking for. So, if I understand
correctly, score file
((eval '("from"
("Author <...>" 1000 nil e))))
should be effectively equivalent with score file
(("from"
("Author <...>" 1000 nil e)))
But it's not. The score file which uses "eval" has no effect. Could you
(or someone) please give some simple example on how to use it?
