if语句可以作为函数调用来实现吗？ [英] Can if statements be implemented as function calls?

问题描述

在发布的代码中，我发现其中一种风格上的惯例是使用：

  if ）{
  

而不是（我的偏好）：

  if（condition）{
  

也可能是不重要的一个，但我想到，如果'if'语句被实现为一种函数调用，那么第一种样式可能是合理的。然后我可以停止反对它。

有人知道一种编程语言，其中if语句是作为函数调用实现的，其中参数是单个布尔表达式？

编辑：我意识到if（）后面的块有问题，我表达我的问题的方式可能太幼稚了，但我对这些答案感到鼓舞

解决方案

tcl是一种语言，它实现 if 作为常规在带有两个参数的构建函数/命令中;条件和要执行的代码块



if {$ vbl == 1} {putsvbl is one}

http：// tmml.sourceforge.net/doc/tcl/if.html

事实上，tcl中的所有语言结构（for循环，while循环等）都是作为命令/函数实现。

One of the stylistic 'conventions' I find slightly irritating in published code, is the use of:

if(condition) {

instead of (my preference):

if (condition) {

A slight difference, and probably an unimportant one, but it occurred to me that the first style might be justified if 'if' statements were implemented as a kind of function call. Then I could stop objecting to it.

Does anyone know of a programming language where an if statement is implemented as a function call, where the argument is a single boolean expression?

EDIT: I realise the blocks following the if() are problematic, and the way I expressed my question was probably too naive, but I'm encouraged by the answers so far.

解决方案

tcl is one language which implements if as a regular in built function/command which takes two parameters ; condition and the code block to execute

if {$vbl == 1} { puts "vbl is one" }

In fact, all language constructs in tcl (for loop , while loop etc.) are implemented as commands/functions.
