A DATE could 現実に be 代表するd as二塁打 in
UNO and therefore a typedef from 二塁打 to a date type would
do. But a typedef cannot be 表明するd in all language bindings. In the
事例／患者 where no typedefs are supported the actual type is used. That is, a
typedef'd date type would be 代表するd as 二塁打 in Java.
The （警察などへの）密告，告訴（状） that the 二塁打 is a date type is lost.
When calling Automation 反対するs from UNO the distinction between
二塁打 and date type is important. Therefore Date
is 宣言するd as struct.
