Design by Contract (DBC, for short). 契约编程

在自己代码中，经常使用assertion去验证你的假设条件。一旦有违背假设的情况，及时crashing  避免问题继续传播，pollute downstream code, make you life much easier when debugging.

It's much easier to find and diagnose the problem by crashing early, at the site of the problem。

再问题已发生的现场（或时候）就及早崩溃，对于诊断和找出问题大有裨益。
