Now, scholars are ingenious in their ability to skirt absolutely the central conundrum of Providence that this poem raises ; and which it raises so insistently and really refuses to let go of; but that doesn't mean that the problem just goes away.

学者们非常精明的,在这首诗里体现出的天意的中心问题上打擦边球,这个观点如此坚决我们无法弃之不管;,但那并不意味着问题就这样解决了。

So in other words, if you terminate these lines early, if you terminate the four loop early, if you terminate an if condition early with that semicolon, the code may very well work; and this is a common source -- of frustration and conundrum because you don't -- because your code looks right and yet it's misbehaving, but that semicolon means stop looking for subsequent lines of related code.

换句话说，如果你用分号过早的终止了这些代码行，如果你过早地终止了那个for循环，如果如此,一个if条件，代码可能可以运行，这就是,挫折和问题产生的源头，因为你没有-,因为你的代码看起来是正确的，但是运行是错误的，那个分号的意思是,停止寻找后面相关的代码。
