Don't ask me what we "could" do.  I don't decide anything.

My own opinion would be not to do that.

If you are really worried about discoverability, then an alias
that speaks to what the function really *does* is more important
than an alias that calls out the main argument type.

`reduce' etc. are meaningful names to anyone used to functional
programming with higher-order functions, but they are not names
that help discoverability for someone not used to that.

Not to mention that the doc string for `reduce' here is not
helpful.  It just reuses the verb "reduce", without describing
anything.  Contrast the Common Lisp one-line description:

 "uses a binary operation, FUNCTION, to combine the elements of
  sequence bounded by START and END."

(Yes, a one-liner is not going to make things crystal clear,
in any case.)


And again, we should, IMO, not introduce things like `some-p',
which overlap with `cl-some' in functionality.  Just have one
such function (for each such proposed conflict), and preferably
have it follow Common Lisp's lead.
