The docstring of the map-elt function from the map.el package (version
3.0) mentions that TESTFN is deprecated because "its default depends on
the MAP argument". However when I try e.g.

(map-elt '(("A1" . 3)) "A1")

it returns nil.

When I add the correct TESTFN

(map-elt '(("A1" . 3)) "A1" nil 'string=)

it does correctly return 3.

So it seems to me that TESTFN is not yet deprecated, or that otherwise I
am understanding it incorrectly. In that case I would label this as a
documentation bug.
