It's not performance this time. Intuitively, labels belong to the same "subordinate" "category" as e.g. semicolons, both not far from comments and white-space. Extra semicolon at the end of a block doesn't change what this block evaluates to. Lone label, I now know, does, which is dangerous. Neglected to have been (temporarily?) commented-out along with its loop (if placed per PBP at the next line) and maybe some further statements. Of course, it's the same weird nonsense, please ignore.
