推荐答案

有什么错在自己的标签和跳转的。现在的问题是，人们往往会滥用他们这确实造成了问题。

There is nothing wrong with labels and goto's in themselves. The problem is that people tend to abuse them which does create a problem.

典型用途的标签

OperationStart:
  if ( !TrySomeOperation() ) {
    if ( MaybeFixOperation() ) { 
      goto OperationStart;
    }
  }

您就需要做出安：我喜欢一些断言'吨击中infitite循环，但给予合理的一系列保障，没有什么内在的错误此代码。

You'd need to make some assertions that you couldn't hit an infitite loop, but given a reasonable set of guarantees there's nothing inherently wrong with this code.
