Greetings fellow monks.

I solved my problem, but I am trying to understand the error message that preceded it, that I might gain wisdom from the experience.

When I leave off the <> operator on the while(<KNOWN_HOSTS> loop on line 83 in the below code snippet, the error is thrown from the close on line 92, instead of the while on line 83.

My question is: Why is the error not thrown from the while on 83?

while (KNOWN_HOSTS) {   # this is line 83
    $inline = $_;
    if (isOneOf($inline,@contexts)) {
        next;
    } else {
        print;
    }
}

close(KNOWN_HOSTS);  # this is line 92
