You have the right idea about functions in general; but chdir() is a
"named unary operator", so it has higher precedence than the ||
operator:
chdir "/any/wrong/path" || die "This will indeed die: $!";
That means that the OP's code isn't so wrong as it may seem, even
though there's surely a better way to write it.
