Hi!

Currently it's not possible to use `seq-some-p' to check if a sequence

contains some `nil' value. For instance:

(seq-some-p #'null '(1 2))

     ⇒ nil

Which is good, but:

(seq-some-p #'null '(1 nil 2))

     ⇒ nil

How to distinguish the two cases?

Two solutions come to my mind: 1) Make `seq-some-p' a pure t/nil

predicate, or 2) Make it behave like `some' in Common Lisp, which is

to return the first non-nil value which is returned by an invocation

of the predicate. So in CL:

(some #'null '(1 2))

     ⇒ nil

And:

(some #'null '(1 nil 2))

     ⇒ t

And even:

(some #'1+ '(5 4 3))

     ⇒ 6

What do you think?
