Probably easiest to do it in two steps, since bracket-matching is a
real chore in a regular expression.

>> input = "[25.0, 26], [30, 31]"
=> "[25.0, 26], [30, 31]"
>> groups = input.scan(/\[.*?\]/)
=> ["[25.0, 26]", "[30, 31]"]
>> output = groups.map {|g| g.scan(/\d+\.?\d*/).map {|n| n.to_i} }
=> [[25, 26], [30, 31]]

Do you really need 25.0 instead of 25? Mixing integers and floats can
be a bad idea. Adjust the 'to_i' call accordingly.
