You shouldn't add or remove elements from an array you are looping over with foreach. Fortunately, you aren't actually using the loop variable $_; even so, you will be accidentally skipping over the element after one you've spliced away, since it will move into the $count position just as you move on to look at $count+1.

Instead, do:

for my $count ( reverse 0..$#content ) { # do stuff with $content[$count], including splicing it out of exis +tence }

    That makes a lot of sense, and explains my confusion concerning why it seemed to work sometimes. Thank you. And thank you to everyone for your rapid responses.
