The adaptive score alist variables.

The adaptive score alist variables.

[Štěpán Němec]

In (info "(gnus)Adaptive Scoring") there is a strange discrepancy
between `gnus-default-adaptive-score-alist' and
`gnus-default-adaptive-word-score-alist'.

While the former is exemplified as

      '((gnus-unread-mark)
         (gnus-ticked-mark (from 4))
         (gnus-dormant-mark (from 5))
         (gnus-del-mark (from -4) (subject -1))
         (gnus-read-mark (from 4) (subject 2))
         (gnus-expirable-mark (from -1) (subject -1))
         (gnus-killed-mark (from -1) (subject -3))
         (gnus-kill-file-mark)
         (gnus-ancient-mark)
         (gnus-low-score-mark)
         (gnus-catchup-mark (from -1) (subject -1))))

the latter is shown as

     `((,gnus-read-mark . 30)
       (,gnus-catchup-mark . -10)
       (,gnus-killed-mark . -20)
       (,gnus-del-mark . -15)))

And indeed, the default value of g-d-a-w-s-a is

    '((82 . 30)
      (67 . -10)
      (75 . -20)
      (114 . -15))

Is this difference (symbols in one case, values in the other case)
significant? If so, that looks like a horrible design. Also, why
should I have to evaluate the mark symbols to actually get to know their
numeric values and be able to adjust the word score alist? (I understand
the marks are character values, but the correspondence is not obvious,
esp. when `describe-variable' gives you the numeric values.)

Looks like larsi did it (last related edits were in 1997), though I
don't know why.  Maybe it was for performance reasons.

You shouldn't have to, normally.  Maybe it just wasn't meant as a
long-term solution.  Sorry I don't know more.

I can't recall, either.  Might be some ... legacy reason...
