- restrictions on labels is back to one-use-per-block. It is useful to
be able to isolate a piece of code (e.g., a state machine) inside a
pair do-end and be sure that its labels do not interfere with external
labels. For those that think that homonymous labels are confusing (with
good reason), simply do not use homonymous labels. It is easy to avoid
and easy to spot.
