Returning a structure like Array[Object] in Ruby

gistfile1.rb

require 'ostruct'

# Given this array[hash[hash]] structure
a = [{"object" => {param1: true, param2: false}},{"object" => {param1: false, param2: true}}]

# I want to return:
=> [<OpenStruct param1=true, param2=false>, <OpenStruct param1=false, param2=true>]

# Current code:
a.map { |k| k.map { |k,v| OpenStruct.new v } }

# Returns
=> [[<OpenStruct param1=true, param2=false>], [<OpenStruct param1=false, param2=true>]]

# It's close... but I don't want the useless extra array wrapping my OStruct object.

Solution for those that care:
use .flatten at the end of line 10!

Better yet, replace line 10 with:
a.map { |k| OpenStruct.new k["object"] }
