Re^2: Avoiding the == blues

You are absolutely correct, of course, but this doesn't work for other languages, or for badly written scripts which generate thousands of warnings that you have to maintain. :)

In some other languages, `if` takes a boolean, which is (deliberately) not what an assignment returns, so `if (x = 0)` doesn't get past the compiler.	[reply] [d/l] [select]

Well, saying "other languages" isn't quite correct, as it's the compiler that will issue a warning, if any. And gcc with -Wall will. It will even catch cases like: `if (x = y)` [download] unlike Perls -w, which will let you do `if ($x = $y)` [download] while keeping silent.	[reply] [d/l] [select]
