I direct your attention to this 1974 paper by Donald Knuth.

I think for as much as it will be used and for clarity and parsing reasons,
label "abc" would be best, but others may disagree. It especially will not work
after the do. It would be hard to detect if it's the first execution token of the
block or a label. Also, I do not think the label would need to be quoted, it
would just be label top.
