Please in the future allow more than just a couple of days for people
to comment on non-trivial patches.

As it happens, I do have a few issues with the change:

  . it slows down code of two very popular functions, because we now
    use EQ instead of a C-level equality operator;
  . it introduces a function that has the same name as a variable,
    which adds a bit to confusion, and also defeats our method of
    reporting in what version was the function/variable introduced
    (try "C-h f"); and
  . I don't think I see the simplification that justifies these
    (admittedly quite minor) downsides

Thanks.
