Dunno if it suggests that, but yes, I've
argued that for a long time. Emacs should
just adopt it as `case'. (It _used to be_
just `case', BTW, but it was in `cl.el'.)
And it wouldn't hurt for Emacs to allow an
optional TEST arg for the equality predicate.
That also serves as the membership predicate,
i.e., for clauses such as this:
((foo bar toto) (handle-foo-bar-and-toto))
(An optional KEY arg isn't needed, since
`case' is simple - it uses the same part of
the input value for all clauses - just apply
whatever KEY selector you need to the input
sexp. Another example of `case' simplicity.)
And adding optional TEST wouldn't bother
any existing uses of `cl-case'. `cl-case
could be aliased to the new `case' (or not).
