As said before you don't need the returns, and you don't need so many
parentheses.
Can you let us know if this works for you?

irb(main):004:0> foo = lambda {|x| lambda {|y| x + y}}
=> #<Proc:0xb7b9c758@(irb):4>
irb(main):005:0> foo.call(3).call(4)
=> 7
irb(main):006:0> puts foo.call(3).call(4)
7
=> nil
irb(main):007:0> puts foo[3][4]
7
=> nil

Jesus.
