Exactly what I needed to do! I ended up with this solution:

[:action1, :action2].each do |action|
  can action, Obj do |x|
    puts "#{action}" # print the given action
  end
end

You can initialize Ability class instance method with action as variable:

#models/ability.rb

class Ability
  include CanCan::Ability

  def initialize(user, action)

    can action.to_sym, Obj do |x|
       #do something with your action (and user?)
    end

  end

end

Now you can initialize new ability passing current action to it:

#application_controller.rb

def current_ability
  @current_ability ||= Ability.new(current_user, params[:action])
end

and apply any rules using action name stored in default parameter :action
