def memoized(name, &block)
  var = "@#{name}"
  if instance_variable_defined?(var)
    return instance_variable_get(var)
  end
  value = yield
  instance_variable_set(var, value)
end

#reset(name, &block) ⇒ Object

Humanoid specific behavior is to remove the memoized object when setting the association, or if it wasn’t previously memoized it will get set.
