Sorry, bad memory. Though there was some opposition, the "=="
proposal was not rejected:
http://austingroupbugs.net/view.php?id=375 was what I was
vaguely recalling.

It's still possible that the next major POSIX spec will have
[ == ] and maybe even [[ ]].

You guys may want to comment on the latest proposal there:
http://austingroupbugs.net/file_download.php?file_id=31&type=bug

as it would make zsh non-conformant.

In particular, it  proposes specifying [[ =~ ]] the ksh/bash
way, that is where quoting escapes regexp operators (
[[ a =~ "." ]] returns false) and [[ < ]] required to use
collation.
