Still missing a negative test (see codecov's analysis in "Files changed" tab).

[jeking3]

I suspect there may be a good reason why the reference return comes before the bool return in the definitions of operator [], so I would recommend using the same ordering for the at() method. It's also possible I'm just being a little paranoid. :)

[akr-akari]

OK, I have changed the order of at().

@mclow this looks good to me, would you like to review it again?
