この場合、C<BUILDARGS>メソッドがないと、Mooseは（ハッシュまたはハッシュリファレンスを期待しているので）エラーを発生させますが、C<BUILDARGS>メソッドを使うとこの呼び出し方に対応できます。

around BUILDARGS {
around BUILDARGS => sub {
my $orig = shift;
my $class = shift;

C<$class->$orig>を呼んでいることに注意してください。これは親クラスのメソッドを呼び出すことによりL<Moose::Object>にデフォルトで用意されているC<BUILDARGS>を呼ぶものです。このメソッドを使うとハッシュリファレンスとただのハッシュを区別してくれます。
