绑定标量变量以及在此问题上的任何绑定变量都需要将其实际数据存储在某个地方。
Note that a tied scalar variable, and any tied variable for that matter, needs to store its actual data somewhere.
这看起来很方便，实际上它与向CLASSPATH环境变量添加目录一样，存在长远的潜在问题。
While this seems convenient, it is also a long-term mistake akin to adding directories to the CLASSPATH environment variable.
