Hi Pierre,

I well understand now that I must use seq-find instead of
seq-some but I think that I will not be the only one being
confused by these functions specifications !

There is a mistake (extra if) in the documentation, I will fix that.

Other than that, is the following less confusing?

  Return non-nil if PRED returns non-nil for at least one element of SEQUENCE.
  If so, return the value returned by PRED.

The previous doc string contains more information: it explicitely says
that it returns the _first_ non-nil (PRED element).

Indeed, what about:

 Return non-nil if PRED returns non-nil for at least one element of SEQUENCE.
 If so, return the first non-nil value returned by PRED.
Yeah better.
The first line with the repetition of 'non-nil' sounds a little poetic.
How about?
 Return non-nil if PRED is satisfied for at least one element of SEQUENCE.
  If so, return the first non-nil value returned by PRED.
