I was able to re-create your symptom on my Win XP platform if the last line "john" does not have a line ending. In other words if the file EOF (End Of File) occurs right after "john" instead of there being a normal "end of line" sequence of characters before the EOF.

my $line =<STDIN> is a line oriented I/O method. It returns a line when it sees the EOL (End Of Line) character sequence. If EOF happens before EOL, then it (added to post: should return the line as it does with C readline) However, in my case this returns "false" so this last "not quite complete line" is not processed.

At the moment, I do not know how to get this unusual "john" last line processed. I am sure that there is a way, but right now I don't know it. Of course in your texteditor, end the john line with "enter" and all will be fine.

Update: The symptoms that I am seeing above are on an ancient Win XP laptop. The result completely surprised me! It would be helpful if the OP can replicate my results.
