模板元编程=解释 [英] Template metaprogramming = interpretation

问题描述

人们是否同意在很大程度上使用模板的声明

元编程技术将C ++编译器转换为C ++解释器（但

仅用于元编程部分的代码）？这不是一个完美的

类比，但它似乎是一个合理的陈述......

人们会同意这样的说法：在很大程度上，使用
模板元编程技术将C ++编译器变成C ++解释器
（但仅用于元编程部分代码）？这不是一个完美的类比，但它似乎是一个合理的陈述......

每个编译器都是一个解释器，如果它可以处理的东西喜欢


int a = 1 + 2 + 3 + 4;


通过创建初始化为10的''a'的定义来代替

a使用

即时操作数执行三次添加的特殊代码。

我不同意这个陈述。它更像是一个超级编译器，因为它可以在编译时预编译代码，而不是在运行时翻译语言

。

Would people agree with the statement that to a large degree, using template
metaprogramming techniques turns a C++ compiler into a C++ interpreter (but
just for the metaprogrammed portions of the code)? It''s not a perfect
analogy, but it seems to be a reasonable statement...

Every compiler is an interpreter if it can handle things like

int a = 1 + 2 + 3 + 4;

by creating a definition of ''a'' initialised to 10 instead of
a special piece of code that performs three additions with the
immediate operands.

I wouldn''t agree with the statement. It''s more of a supercompiler as it
can precompute code at compile time as opposed to translating language
at run time.
