DSL Boilerplate

We want something like this:

class LakeSuperior
  include LakeDSL

  lake_name 'Lake Superior'
  fish 'trout'
  fish 'northern pike'
end

And we have to write boilerplate like this:

module LakeDSL
  # dump code
  def lake_name(name = nil)
    return @lake_name if name.nil?
    @lake_name = name
  end

  # super annoying
  def fish(name = nil)
    return @fishes if name.nil?
    @fishes ||= []
    @fishes << name
  end
end
