ALGOL 60 had alphanumeric labels, and there was a consensus that
allowing numeric labels had been a mistake.

I've had very few cases where a GOTO out of block[1] was the cleanest
way to code something. I see its greatest value as implementing new
control structures, e.g., a CASE statement before SELECT came along.
