Re^4: Forking sub inside a module

Maybe it's just me, but I find
while (wait != -1) {}
more natural than
while (-1 != wait) {}
since 'wait' is what I want to check :o)

It helps to debug typo mistakes (language independent). If you was doing a regular compare '==' but used '=' instead, then 'wait = -1' will assign -1 to wait which could cause run time problems later on. However, if you do '-1 = wait' the compiler will throw a syntax error because you are trying change a constant.	[reply]

Good point, except you "can't modify wait in scalar assignment" either, or atleast that's what perl says when I try. For variables though, I see what you mean. -- Time flies when you don't know what you're doing	[reply]
