The answer is simple:closures do not store static values. Instead,they store references to the variables present inside the scope chain. In this way, even if the outer function dies, the inner function, that is a closure, still has access to its parent variables. 绘制作用域链 步骤: 看整个...
If I’m a compiler in the act of compiling print-y (above code snippet) in a static language, then I know the scope I’m running in (hence static scope). I know that y is bound to the global variable, and I can replace that y with a direct location of x01 in the assembly I...
However, no discussion on static testing would be complete without an explanation of what its counterpart dynamic testing means. Dynamic testing is validation, the other “V”. We will also learn about the key differences between the two techniques. Table of Contents: Static And Dynamic Testing S...
using System; using System.Reflection; using System.Reflection.Emit; class DefinedDynamicAssemblySnippet { public static void Main() { AppDomain currentDomain = AppDomain.CurrentDomain; InstantiateMyDynamicType(currentDomain); // Failed! currentDomain.AssemblyResolve += new ResolveEventHandler(MyResolveEventHa...
Other languages that push forward the opposite approach—dynamic type checking—have come along over the years. Dynamic type checking contradicts the idea that the type of a variable has to be statically determined at compile time and can never change while the variable is in scope. Note, howeve...
(e.g, fire, loss of electrical supply, etc). Those faults add a combinatorial characteristic to the problem, that is tractable in practice depending on the scope of the analysis: Usually, parts of the plant are analyzed one at a time and only a reduced number of variables are allowed to...
surrounding static scope, whether it's a single object marked dynamic or a whole block. And it needs to be predictable with respect to the scoping rules in both forms. I can't help but think about how statement lambda expressions and anonymous methods reach out into the surrounding scope as...

a substantial reduction in heat dissipation. However, we should keep in mind that the potential heat reduction depends on the range of supply voltages that can be applied: as the upper voltage limit has dropped from 5V a few years ago to just over 1V, the scope for savings is diminished....
However, the lack of domain knowledge of the underlying JIT compiler could limit the class and scope of optimizations that the language VM can perform. For example, a language VM might (or might not) decide to inline certain methods into hot method bodies depending on runtime heuristics that ...
