class Fluent
  def initialize(cache: nil)
    @cache = cache ? cache : []
  end

  # Reflection
  def method_missing(name, *args, &block)
    _(name.to_s)
  end

  # Build the cache, and handle special cases
  def _(name)
    Fluent.new(cache: @cache.push(name))
  end

  # Final method call
  def method()
    @cache
  end
end
