Subject: how to un-ragged a 2D array?

Rubies:

Here's a ragged array:

  [ [ 1    ],
    [ 2, 3 ],
    [ 4    ],
    [ 5, 6 ],
    [ 7    ],
    [ 8    ] ]

How, with the tightest, or most modern, or coolest statements, can we turn it 
into this?

  [ [ 1, 1 ],
    [ 2, 3 ],
    [ 4, 4 ],
    [ 5, 6 ],
    [ 7, 7 ],
    [ 8, 8 ] ]
