I like this. I haven't spent a lot of time on thinking about
ambiguation. But I think we're safe there. '@' is not overloaded much
like ':', '^' or '~'.

I'm a bit reluctant to this. It looks like incomplete syntax to me as
'@' has always been followed by '{'. Can we have the lone '@' candy
but reject master@ and HEAD@? There's no actual gain in writing
master@ vs master@{0}.

And this does not explain about HEAD@ or master@. But because I prefer
the candy part only. This documentation part looks good :)
