Rough shot at what some Lattice Cell code might look like

example.rb

require 'lattice'

class ApplicationCell
  include Lattice::Cell
  # Other custom stuff
end

class Person < Struct.new( :name , :birthday )
end

class Address < Struct.new( :month , :day , :year )
end

# Or maybe more like this for immutable magic
#
# class Person < Lattice::ValueObject
#   property :name
#   property :birthday
# end

class PersonCell < ApplicationCell
  def update_address( person , address )
    # performs data transformation 
  end
end

example2.rb

require 'lattice'

class Person < Struct.new( :name , :birthday )
end

class PersonCell
  include Lattice::Cell

  # ONLY here for example
  # Probably defined in `Lattice::Cell`
  def call( *args , &block )
    desired_method = args.shift
    # Other things could happen here like turning params into value objects
    send(
      :future,
      desired_method,
      *args,
      &block
    ).value
  end

  def update_address( person , address )
    # performs data transformation 
  end
end

class PersonResource < WebMachine::Resource
  include Lattice::Cell

  def process_post
    PersonCell.new( params ).call :update_address
  end
end
