How can I get a list of checkout history?

As you know, I can checkout the Nth checked out branch via this syntax:

$ git checkout @{-N}

Is there a built-in mechanism to get a listing of previously checked out refs? Basically, this would be similar to 'history' command in linux where instead of actual commands, it lists like this:

HEAD@{-1}: master HEAD@{-2}: topic1 HEAD@{-3}: 3f556e9 (detached)

Seems like reflog should be able to do this, and maybe it can, but I'm not sure. Any tips? I'd be fine making a convenient alias for this if it ends up being a series of piped commands.

Thanks in advance.
