I'm sure. It's not. But either of this works.

        substr($_, -1) = '';

        $chopped = substr $_, -1, 1, '';

chop() is a speed optimization for a (currently) pretty uncommon task:
removing the last character of a string. Why not the first character,
for example? The string equivalent of shift()?

Only people who insist that ALL lines in a text file should end in a
newline, would still prefer use it.
