Re^6: $_ not set in while <>

For those wondering:

Misunderstanding 1:

dense: Having relatively high density. Slow to comprehend; of low intelligence.

Misunderstanding 2:

That's why he didn't care about checking defined for the line, since undef is a way to indicate EOF for files.

But the special power of while(<>) is that he could call it on a file in @ARGV for testing those manual inputs

What are you talking about. We were both discussing density, and we were both talking about a terminal (or at least didn't exclude it). Perhaps you think a terminal can't return EOF? Yet that's a common occurrence. I didn't say those things you tried to put in my mouth cause I didn't mean those things. A program that fails to handle a common occurrence by going into an infinite loop is bad, and a style that makes this kind of error easy and hard to notice is not that great. Simple as that.
