Re: [PATCH] Add new @ shortcut for HEAD

Junio C Hamano wrote:

If you accept only "@" but not "master@", that behaviour needs a
wrong world model to understand and justify (one of which is "@ is a
synonym for HEAD").  If your rule is "In $anything@{$n}, you can
drop {$n} when $n==0", then HEAD@{0} becomes HEAD@ and master@{0}
becomes master@, and @{0} becomes @ naturally.

Besides, you're going in the wrong direction this time.  You are
trying to fit an explanation to something that is useless.  How is
master@ useful?
